Why Use LED Lighting in Parking Lots and Garages

By | News | No Comments

When it comes to illumination, parking lots and garages present a challenging environment. This is because the illumination system must accommodate both pedestrian and vehicular traffic, address public safety concerns, endure harsh operating environments, and consider lighting quality issues.

 

The wrong lighting system, for example, can cause excessive shadows in parking areas, which is a safety hazard to pedestrians and motorists trying to navigate barriers and obstacles.

 

In the past, High-Intensity Discharge (HID) light fixtures have been used to ensure a bright and well-lit pavement, as it is one of the few fixtures that can emit light on a wide scope.

 

The downside is that it costs a lot of money because of its huge energy consumption. You can just imagine the electric bill you would have to face each month for the HID lights alone. Since there will be more than one fixture within the parking lot and garage, one can expect a staggering electric bill.

 

Some businesses opt to use low fixture mounting heights to achieve the desired illumination at a lower cost. However, this will require more fixtures to be used, resulting in glare problems.

 

Such concerns, however, have been resolved with the use of LED lights, a fixture with better features and more benefits.

 

Higher Color Rendering Index

One of the best companies in the market for LED lighting is Worldbond. Their LED lighting output can rival that of other LED and HID counterparts. Worldbond LED’s, in general, offer a superior choice in parking lots and garage lighting because their LED’s have a higher color rendering index.

 

Because of LED’s higher color rendering index, you get a truer white light than an HID lighting fixture is capable of. It provides more accurate colors, making it a perfect lighting option for true color as in car dealerships. It has brighter illumination without the high energy consumption.

 

Longer-Lasting Fixtures

The LEDs’ wonderful white light will not change or fade over time. Rated to last much longer than traditional HID lighting fixtures, you don’t need to change lamps frequently, reducing cost in manpower and labor. In fact, it has a life expectancy of 8 to 20 years

 

Lower Energy Costs

In addition to having a brighter illumination, LED lights have lower energy consumption saving more than 50% in consumed energy. As an example, a traditional HID system with a 150w Pulse Start Metal Halide (PSMH) lamp, uses 185 watts, but its equivalent LED system only uses 70 watts. Given that the HID only has life hours of 15,000 while the LED has 60,000 hours, an overall savings of 63% can be realized.

 

Lower Maintenance Cost

Because of its higher life expectancy rate, you will be able to save on maintenance costs. If you don’t need to replace bulbs more often, you won’t have to hire people to do the work. There is no need to take care of LED bulbs either. You just need to make sure they are protected against harsh elements to prevent premature damage.

 

Better Security

With an illumination equivalent to or greater than HID lamps, expect heightened visibility in and around parking lots and garages. No need to worry about excessive shadows or being unable to see all the parked cars clearly.

 

Without a doubt, using LED lights in parking lots and garages will work to your advantage. As a distributor for WorldBond, we are experts in LED lighting, contact us today for more information.

Understanding Harmonic Filters and Their Role in Power Factor Correction

By | News | No Comments

In an electrical system, the term power factor is the ratio of usable real power to non-usable apparent power sometimes called reactive power. It not only controls energy consumption but also how that energy consumption is billed.

 

The lower the power factor the higher the required necessary current draw, which will require a more robust infrastructure and the use of appropriately heavier gauge wires to minimize the dissipation of power. This means that on-premises utility usage will be more costly, and facilities operating with low power factors will be charged at a higher usage utility rate than facilities with high power factors.

 

Fortunately, there are ways to correct sub-par operating power factors and greatly reduce or eliminate frequency harmonics to ensure higher cost efficiency of an operating electrical system.

 

There are two scenarios causing power factor displacements – operating power factor and harmonic power factor. The first displacement is caused by any inductance in an electrical load, (such as a motor) causing the delivered current to be out of phase with the supply voltage, while the latter displacement results from any non-linear switching of the utilized supply voltages, such is the case when using power semiconductor devices and rectifier circuits.

 

For an electrical system to function properly, any harmonic resonance present and/or harmonic distortion must be eliminated

 

When there is a large supply of individual currents from a number of harmonic current sources, the system could resonate. This is especially true if one of the harmonic frequencies of the current sources coincides with the resonant frequency created from the combination of the supply transformer’s and the capacitor circuitry combination which is being used for power factor correction.

 

The large flow of current going to a major supply transformer (such as in a data center) can lead to a large harmonic voltage distortion. This event increases the risk of increased heating which will cause the loss of some of the transformer’s power output, possible malfunction of connected equipment, possible premature failure of other connected power factor correction capacitors and motors, and interference in some communication systems.

 

Harmonic Filters – A Practical Solution

To reduce or eliminate harmonic resonance and distortion, a true harmonic filter needs to be used at strategic operating circuit points.

 

What is a harmonic filter?

As previously mentioned, harmonic filters are used to eliminate harmonic distortion caused by excess currents in and out of appliances. It can prevent large quantities of harmonics from causing damage to equipment, downtime of operation, and preventing an increase in operating costs.

 

What is a harmonic filter made of?

The interior of a harmonic filter is made up of an array of resistors, inductors, and capacitors that are capable of deflecting unwanted harmonic currents, sending them to ground. Some of these filters are designed to deflect harmonics of a specific frequency or frequencies.

 

What are the various types of harmonic filters?

Passive Harmonic Filters – These filters are typically used in industrial installations with loads representing more than 500kVA. These filters require power-factor correction during installation.

 

Active Harmonic Filters – Also known as active harmonic conditioners, these filters are often used in commercial installations with loads less than 500kVA. They help to reduce current distortion that could lead to equipment heating and circuit overloads.

 

Hybrid Filters – A system that combines passive and active filters for industrial installations with loads more than 500kVA. It has the advantage of the previous two types of filters and covers different power and performance levels.

 

Each of these options has their place in the market. It is important that a user identifies the amount of harmonic distortion that needs to be eliminated before a filter is chosen. Active filters, for example, are ideal when there is more than one type of load present, such as UPS, VFD, and DC drives

 

These various types of Harmonic Filters are readily available from Staco Energy. Staco Energy is an 80 year old midwestern company engaged in designing and supplying harmonic filters, voltage regulators, and UPS power  conditioning equipment. Please contact Peninsula Technical Sales for further information regarding what type of harmonic filters might be appropriate for you.

Why Should You Choose a Transformerless UPS?

By | News | No Comments

Most, if not all, companies nowadays know that they should use an uninterruptible power supply (UPS) device along with their computers, servers, telecommunications equipment, and other electronics. This way, in case an unexpected power outage happens, their equipment won’t shut down right away. This can help prevent data loss (which can greatly harm businesses of all sizes) and even keep accidents and serious injuries at bay. Below we will get into why a transformerless UPS may be a better option for you.

 

Simply buying a UPS device isn’t an easy process either. There are several types of UPS available on the market, and business owners and managers must choose the right product for their needs.

 

The traditional option is the transformer-based UPS which, as its name implies, relies on a built-in transformer to increase or decrease the output voltage. The more modern choice is the transformerless UPS, which is made possible through modern technological innovations, especially with the development of the Insulated Gate Bipolar Transistor (IGBT) device. In a transformerless UPS, the transformer is taken out of the design and is replaced with another component (such as a DC converter) that fulfills the requirement of the critical load.

 

The question now is this: should you replace your transformer-based UPS with a transformerless one? This is not easy to answer since different companies and applications have different UPS needs, but you’ll want to take a look at transformerless UPS devices since they offer the following benefits:

 

They’re physically smaller

Because it no longer has to house a transformer, the transformerless UPS has a smaller form factor than its traditional counterpart. This makes it an ideal choice if you have limited space in your office or data center and are looking for equipment that doesn’t take up a ton of room. If weight is an important criteria in your equipment setup, you’ll be happy to know that transformerless UPS devices are lighter than transformer-based ones.

 

They are modular

Traditional transformer-based UPS devices are freestanding units that are usually placed on the floor. Transformerless UPS products can revolutionize this practice by making rack-mounted modules a possibility. You’ll no longer have to keep large and clumsy units underfoot; instead, you can simply get a cabinet and place a single plug-in UPS module on the shelf. As your business expands and your need for UPS capacity grows, you can just get another UPS module and plug it into the existing system. It’s an easy way to upgrade your IT resources without interrupting your equipment’s power supply, dealing with more messy cables, and needing more floor space.

 

They’re more energy efficient

According to expert calculations, transformerless UPS devices have higher energy efficiencies than the traditional options, 99% versus 94% — but only if they are loaded at more than 40 percent of their capacity. If you’re planning to use 50 to 60 percent of your UPS’s capacity (or even higher), you’re better off choosing transformerless devices since they’ll help you consume less power and reduce your utility bills over time.

 

 

These are some of the benefits offered by transformerless UPS devices. If you’ve decided to opt for a transformerless UPS but don’t know which model to choose, contact us at Peninsula Technical Sales by E-mail sales@pentech.com or by calling us at 650-965-3636. We welcome you to visit our web site at www.pentech.com.

electronic warfare

Here’s What You Need to Know About Electronic Warfare: WideBand Systems, INC. / Akon, INC.

By | News | No Comments

When people think of warfare, they usually imagine situations wherein soldiers attack each other with guns, bombs, tanks, and other military weapons, firearms, and vehicles. However, while this type of warfare still exists nowadays, many military units have moved on to a different kind of battle: electronic warfare.

 

What Is It?

Electronic warfare or EW refers to any action that involves the use of the electromagnetic spectrum or any other kind of directed energy to attack an enemy or defend oneself. The process normally uses radio waves as well as laser light, and specific activities can involve confusing the enemy’s electronics systems and disabling their equipment.

 

“Listening” to the enemy is also important in electronic warfare; with the right equipment, military units can zone in on the enemy’s radio signals and gather important information. In this scenario, it’s clear that electronic warfare is the modern-day equivalent of intercepting runners and carrier pigeons.

 

Defense is likewise an essential factor. By using the right techniques, the military can prevent electronic attacks from enemies and make sure they have stable, unimpeded access to the electromagnetic spectrum. This, in turn, ensures that they always have reliable communications and that they can quickly and easily share information with their troops. EW methods can even help detect an incoming missile as early as possible and give military units enough time to take the right steps and minimize loss of life or property.

 

Electronic warfare has become increasingly important in the recent years. As the military becomes more reliant on communications that are based on the electromagnetic spectrum, they have an increased need to protect their communications system from their opponents as well as more opportunities to interfere with enemy communications.

 

Digital Frequency Discriminators in EW

Numerous types of equipment are needed to make electronic warfare a reality, and one of these is the digital frequency discriminator or DFD. This device is used along with an instantaneous-frequency-measurement receiver (or IFM receiver) to determine the frequency of the signals obtained from the enemy. Knowing this is important since it allows military units to determine the frequency they should use to confuse or disable the enemy’s communications system.

 

  • Digital frequency discriminators are built with microwave mixer-based correlators at their front end. These correlators take the incoming signal and convert it into voltage that is equivalent to the frequency of the incoming signal. This voltage is then processed by the analog-to-digital converter that’s found in the IFM receiver. The receiver uses dedicated software to make calculations and determine the frequency of the incoming signal as well as its amplitude, time of arrival, and pulse width. Most DFDs and IFM receivers can process signals that fall between the 0.5 to 18.0 GHz bandwidths. WideBand Systems’ and Akon Inc. Digital Frequency Discriminators (DFD’s) are integrated microwave/video/digital assemblies which provide digital encoding of wide band RF input signal frequency data for pulsed or CW RF signals. These DFD designs represent the state of the art in the precision measurement of RF frequency, and are the culmination of more than 30 years of incremental design improvements to the basic binary correlator DFD. Both WideBand Systems (0.5 GHz to 18 GHz DFD) and Akon Inc. (4.3 to 5.3 GHz DFD) are state of the art DFD’s are used in mission sensitive applications around the world.

 

Contact Us Today

It’s important to note that a wide range of digital frequency discriminators and IFM receivers are available nowadays. This means that clients who want to buy these products should have a deep understanding of their specs and have enough time to browse through dozens of hardware options.

Here’s What You Need to Know About Distributed Antenna Systems : Integrity Microsystems

By | News | No Comments

Modern technology allowed cellular information to be faster, stronger, and more able to keep up with the demands of users. Unfortunately, there are locations and signal densities wherein processing information of these signals is not enough to satisfy users’ needs. In these cases, network owners and managers need to find a way to provide additional cellular coverage. Distributed antenna systems are a way to bolster cellular coverage and capacity by installing managed hubs and multi-band antennas precisely where demand is greatest.

These systems are composed of antenna nodes (also called radio heads) that serve as signal repeaters and are strategically placed around the target area. Each of the nodes is physically connected using cables to a communications hub which, in turn, is connected to the base station of the wireless carrier.

 

Benefits of Distributed Antenna Systems

Why should DAS be used instead of a single antenna? There are several reasons to invest in these systems, such as those below:

 

  • It works in a limited space — If one needs additional cell coverage but don’t have enough space for a traditional cell tower, installing a DAS network is a good choice. The system won’t take up much room since each node must be placed in a different location instead of being grouped in one large area.

 

  • It improves cell signal — In a large venue (such as a mall or a sports arena), people won’t enjoy good cellular signal if they’re sitting or standing far away from the single antenna. Having a DAS network will fix this since the strategically placed radio heads ensure that most people in the area have a direct line-of-sight channel with at least one antenna node.

 

  • It can support multiple bands —  DAS have the ability to provide multiple band coverage supplied by different wireless carriers. This is a great thing to have particularly if you need to increase cellular coverage in a large area, such as sports arenas or music festival venues.

 

Types of DAS

There are two main  types of Distributed Antenna Systems categorized in terms of implementation: passive or active.

In passive Distributed Antenna Systems, the network obtains cellular signals from the antennas placed on the roof then distributes the signals throughout the area using leaky feeder cables. It’s called the passive approach since the network simply “leaks” the signal to the areas where radio heads are located.  Since passive DAS does not use any electronic components between the antennas and base station, only a coaxial cable there is no amplification and the  antennas gradually lose signal strength the further they migrate from the base station.

In active DAS, the network also gets cellular signals from roof-based antennas, but it distributes these signals by using fiber cables. Active-repeater amplifiers are located throughout the network and boost the signals that pass through them.  An active setup is more commonly used when there is a large area to cover as remote hubs can be placed away from the base station.

 

DAS networks are ideal for places that are densely populated or frequently visited, such as malls, sports venues, commercial buildings, college campuses, hotels, and apartment buildings. Integrity Microwave in Argyle Texas provides high performance low profile DAS. They offer single band, dual band, trio band, quad band, and omni-directional DAS networks and can provide businesses in different  venues with the right products and services.

Automatic Voltage Regulators: Staco Energy

By | News | No Comments

There are four  types of automatic voltage regulators:  Ferroresonant, Tap Switching, Limited Range Variable Transformer. and Variable Transformer Buck-Boost.

 

Ferroresonant constant  Variable Transformers

These types of automatic voltage regulators use a capacitor in series with the transfer coil and tend to be high impedance devices that are sensitive to load changes and do not handle high input  loads very well. They can interact with switch mode power supplies to produce transient and electrical  noise on the output and their resonant circuits make them particularly sensitive to frequency changes. When applied cautiously these units can prove from  2-5 % output regulation, load isolation and noise attenuation.

Tap switching Transformer

TAP Switching Transformer based regulators monitor output voltage and  use solid state switching circuits for changing the transformer taps on a fixed ratio transformer. These units tend to provide only 3-5% output regulation as the number of taps used are minimized to control cost.  Although these regulators are extremely fast, this fast response time can often create instability when powering equipment with switch mode power supplies and their output waveform tends to produce harmonics and radio frequency interference.

Limited Range Variable  Transformers

Limited range variable transformer regulators use variable transformers to directly control the output voltage of the regulator. This places the variable transformer’s vulnerable brush and brush track directly in the power path of the regulator subjecting these critical components to system stresses which can lead to possible premature regulator failure. Applications with high overload cycling might require the unit to be over-sized, and with the variable transformer brushes in the power path electrical noise can be introduced  into the system. While limited range variable transformer  regulators can provide  +/- 1 to 3% output voltage regulation they tend to be larger than the Var Tx Buck-Boost Regulator, as manufactured by Staco, that offers  +/-1  % output regulation.

Variable Transformer  Buck-Boost  V

The buck-boost transformer is a fixed ratio isolation transformer capable of high current capacity at low voltage. The ratio of the buck boost transformer is determined by the amount of voltage needed to buck or boost the input line voltage to maintain the specified output level. The buck boost transformer secondary is wired in series with the load and the transformer primary winding is connected across the variable transformer’s “center tap” and brush terminals. Depending on which side of the center tap the variable transformer brush is positioned, the variable buck-boost transformer system will add to “boost” or subtract from “buck” the input line voltage.  The further the variable transformer is from the “center tap” the more bucking or boosting of voltage will occur.

The key to the proven reliability and long trouble free service life of a Staco Voltage Regulator is in the combination of a motor driven variable transformer with buck-boost transformer technology. The only active component in the main power path of the voltage regulator is the secondary winding of the buck-boost transformer. Staco Energy manufactures and supplies this type of voltage regulator. This gives the Staco Energy regulator the advantage of being able to withstand substantial current overloads while protecting the variable transformer brushes, which are the most vulnerable component in any variable transformer system, as they are completely isolated from overload conditions by the buck-boost transformer.

Due to transformer inefficiency above rated design, the amount of current that the buck-boost transformer can induce across to its primary winding and into the variable transformer circuit is dramatically decreased as regulator overload current increases. The controller monitors the regulator’s output voltage and then uses these feedback signals to determine drive commands for the variable transformer motor interface circuit. The controller is designed to adjust the motorized variable transformer to provide a 21% or better output voltage regulation over the entire input voltage range. Staco Energy offers two types of controllers. The solid state type LRC controller which is standard on type AVR (automatic voltage regulators) and the microprocessor type MP controller which is offered as standard on all MVR voltage regulators and is available as an option for Automatic Voltage Regulators.

 

Applications for Automatic Voltage Regulators

Broadcast: regulation for broadcasting transmitter sites and studios

Commercial: High rise building whole floor regulation or power condition, input voltage regulation for elevator control, large A/C chillers, lighting and other sensitive non-critical systems.

Industiral: industrial automation, process control, CNC, factory robotics, facility level of point- of -use , heavy load machinery regulations.

Marine: Deck sides or shipboard voltage regulation and power conditioning.

Medical Medical imaging: x-ray , CAT scans and MRI power conditioning: building or whole floor regulations.

Mobile: Commercial broadcast and military mobile communication trucks, trailers and shelters.

 

Staco Energy

Staco Energy has been in the AV Voltage control and regulation field since 1937. They are built for long term reliability and trouble free operation. The key to the proven reliability and long trouble free service life of a Staco Voltage regulator is the combination of motor driven variable transformer with buck boost transformer technology. Staco Energy transformers have an excellent accuracy: they maintain a constant output voltage within +/-1% or better regardless of input voltage variations from +10—20% and Staco regulators cause no waveform distortion and add no harmonics to the system. For further information call Peninsula Technical Sales at 650-965-3636 or visit our webpage. We are happy to assist you in any need you may have for power condition equipment.

Fast-Switching Synthesizers – Wide Band Systems

By | News | No Comments

Frequency synthesizers were not widely used until the 1970s and 1980s but, over time, they have become an important part of radio-frequency equipment and development. Today, they’re used in numerous devices and electronic equipment including televisions, mobile phones, GPS navigation systems, and cable TV converter boxes. They are also manufactured by a number of different companies including Wide Band Systems.

 

Kinds of Frequency Synthesizers

Frequency synthesizers can be categorized according to their architecture. Direct frequency synthesizers are implemented through the creation of a waveform without the use of frequency transforming elements. Indirect frequency synthesizers, on the other hand, use an oscillator (which is controlled by other signals) to generate the final output.

These can be further divided into analog or digital synthesis. Direct analog synthesis uses mixers, multipliers, dividers, RF switches, and fixed-tuned filters, which is why it’s nicknamed the “mix-filter-divide” architecture. The downside of this method is that it produces high amounts of spurious signals, which requires many levels of filtering and increases the overall cost. Indirect analog synthesis, on the other hand, adds a mixer to a phase locked loop to place an offset that’s equal to the frequency created by the reference oscillator.

Direct digital synthesis or DDS is the most widely used technique nowadays. It stores a version of the required waveform then creates the desired signal frequency through phase-advanced increments. This process promotes better output control, frequency agility, and phase noise, making it a better option than phase locked loop systems. Indirect digital synthesis, meanwhile, is based on a phase locked loop, and it adds a digital divider into the system to change the output signal’s frequency.

 

Switching Speed and Accuracy

Aside from architecture, another thing to consider when choosing frequency synthesizers is their switching speed and accuracy. Switching speed refers to the amount of time between the moment the request for the next frequency is made and the moment the correct frequency output is accurately created. Generally, fast-switching frequency synthesizers are preferred especially in commercial and military applications.

Fortunately, many companies now offer fast-switching synthesizing equipment, and one of the best manufacturers is Wide Band Systems. Their fast-switching synthesizers have a typical switching speed of 3μsec and frequency accuracies to 1Hz. They can be calibrated from 0.5 GHz to 18 GHz or any frequency in between this range, allowing clients to have a frequency synthesizing system that best suits their needs. The equipment can be used in commercial and military systems and utilized in a wide range of applications, such as signal jammers and simulators, unmanned aerial vehicles, and automated test equipment.

 

Wide Band Systems

Wide Band Systems has fast-switching synthesizers that are also used in electronic warfare (EW). Their frequency coverage, fast switching speed and precise frequency accuracy makes them an ideal choice in EW systems since they can detect a wide range of threat emitters. With maximum spurious signals of -60dBc and maximum harmonics of -26dBc, they can provide clean signals and keep up with the demands of sophisticated systems.

 

The best thing about synthesizers from Wide Band Systems is that they can be configured to your exact specifications. If you already have a set of requirements in mind, or even if you’re still in the process of determining what will work best for your application, contact us here at Peninsula Technical Sales. With our technical knowledge in frequency synthesis, plus our expertise in Wide Band Systems’ products, we can help you choose the best possible configurations for your fast-switching synthesizer.

LinearMicroSystems ASICs

Here’s What You Need to Know About ASICs- LinearMicroSystems

By | News | No Comments

An Application Specific Integrated Circuit — commonly known as ASIC — is a type of microchip that’s specially designed for certain applications or purposes. You can contrast it with general integrated circuits (such as your computer’s random access memory chips), which are designed to tackle several tasks at the same time. ASICs are currently used in a wide range of devices and machines, including smartphones, personal digital assistants, digital voice recorders, Bitcoin-mining hardware, and even implantable medical devices. They are also manufactured and designed by a number of different companies, like LinearMicroSystems.

 

Custom Designed

ASICs can be divided into three categories. The first is a full-custom design, which means that every component and layout is designed from scratch to fulfill a specific application. Each of the microchip’s photolithographic layers is fully defined by the designer, and his design is strictly followed during the manufacturing process.

The second category is a semi-custom design (also known as gate-array design). Semi-custom ASICs use pre-defined diffused layers and use wafers that are already held in stock; the layers are interconnected with each other in a special way to create microchips that fit the client’s specifications. They are less expensive than full-custom design ASICs and have shorter production times.

The third category is a structured design (also known as platform ASICs). ASICs that belong under this category use silicon with pre-defined characterization as well as pre-defined metal layers. Using pre-manufactured components effectively shortens design and production times and lowers manufacturing costs.

 

Manufacturers

Because of their customized nature, ASICs are more expensive to manufacture than standard logic integrated circuits. However, the cost is usually worth it because they provide several benefits. They have faster speeds and better performance than generic models since they are designed to tackle one task and do it well. They can also be built to use very little operating power, which is a huge advantage for the end users using batteries  since they can run their device for longer hours on a single charge and won’t need to recharge it often.

Recent innovations have allowed manufacturers to make ASICs smaller in size. They can now also be built with more than a million logic gates, which means they can offer advanced functionalities and handle complex tasks than older ASICs. Modern ASICs can be produced with analog, digital, mixed-signal, and/or radio-frequency (RF) functions, allowing manufacturers such as LinearMicroSystems to create a complete system on chip or SOC. SOCs require minimal external components and can often function properly on their own, which is why they’re preferred by most device manufacturers. By using an SOC, it’s possible to create speedy and powerful devices with a slim, streamlined design.

 

LinearMicroSystems, Inc.

If you need dependable and high-quality ASICs, consider getting them from LinearMicroSystems, Inc.. They’re a trusted semiconductor company that offers a range of analog, mixed-signal, and radio-frequency ASICs for different applications. They have one-stop shopping for all ASIC’s needs including development, prototyping, qualification & production; analog, mixed-signal & digital capabilities along with technical consulting, participate in roadmap discussion & strategic planningLinearMicroSystems can help with both development and production and have in-house facilities for wafer and package testing as well as quality assurance.

Power Quality and Why It’s Important

By | News | No Comments

Power quality is a measure of the electrical network or grid to provide “clean” and stable power A characteristic of good electric power quality is the steady voltage supply where the frequency of the supply remains close the rated value.

Today, energy demands vary and as such, there are energy using  loads that cause disturbances on the grid resulting in a deviation of voltage from the specified parameters. A number of industries suffer from poor power quality which results not only in a rise of energy and production disturbances but also higher energy costs. Sensitive equipment is the usual victims of poor power quality.

Effects of Bad Power Quality

Bad power quality can negatively impact large industrial complexes, data centers, sensitive medical machinery, or impact small businesses and even households in a number of ways. It can reduce the speed of production in businesses, it can damage sensitive equipment, and it can effect efficiency and increase costs. Bad power quality also results in increased energy consumption which isn’t good for either homeowners or business people.

Causes of Electrical Disturbances

An unstable energy load not only causes electrical and production disturbances, it also wastes energy. This is one of the major problems in the electrical environment. These are the common behaviors that cause problems:

  • Harmonics – can be caused by variable speed
  • Network unbalances – can be caused by variations in the load. When the load on one or more of the phases is different than the other(s), unbalanced voltages will appear.
  • Transients- a change in the steady-state condition of voltage, current, or both. Transients are important because any power system must be equipped to handle peaks and other short-duration things in addition to the steady state power.
  • Voltage variations –are sags, swells, dips, and brownouts occurring when the line voltage is higher or lower than the nominal voltage for a short period
  • Flicker- can be caused by welding equipment, shredders, mills and EAF operation.

 

Power Conditioner

A power conditioner is a device that can improve the power quality delivered to electrical load equipment. Also known as line conditioner, these devices delivers proper level voltage to equipment so they can function properly. In short, a conditioner works to ensure that a smooth sinusoidal AC wave is maintained.

Power conditioners are often linked with voltage regulators, which also improve the quality of power through power factor correction, noise suppression and impulse protection. Conditioners can regulate and clean AC power by making power adjustments and removing issues such as noise, sags, surges, spikes and frequency irregularities – these are problems that can damage or really affect the performance of an equipment load.

The size and features of a power conditioner differ. For instance, there are machines developed to supply nominal voltage regulations while there are some made to protect against a range of power quality issues.

Staco Energy specializes in providing power conditioner equipment including power factor correction banks which reduce poor power factor penalties and Active harmonic Filters which eliminates broad spectrum of harmonics on a distribution circuit.

High Frequency Oscillators

By | News | No Comments

5G is the next-generation in wireless broadband technology. It will perform better than the current standard, 4G. Signal technology has also been improved for 5G enabling it to provide even greater coverage. These changes will enhance pervasive computing and the Internet of Things. Although 5G is scheduled for launch in 2020, a number of manufacturers are starting to incorporate elements of the standard into their products, like high frequency oscillators.

5G is expected to operate at higher frequencies and as such, need the high frequency oscillators to generate radio frequency signals in the millimeter wave range.

Oscillator

An oscillator is an electronic or mechanical device that produces continuous, repeated and alternating waveform without the need for input. It’s the job of an oscillator to convert unidirectional current flow from a DC source into AC. A number of devices use oscillators including clocks watches, metal detectors (all mechanical examples), radios and computers (both electrical examples).

The frequency of the output signal is how an oscillator is characterized. For example, a low-frequency oscillator may generate a signal less than 100 Hz. An audio oscillator is an example of a low frequency oscillator producing frequencies in 16 Hz to 20 kHz range. An RF oscillator produces signals in the 100 kHz to 100 GHz range. Synergy Microwave is a leading provider of Oscillators in this range of frequencies

Electronic Oscillators

Electronic oscillators are used in audio-frequency equipment, computers and wireless receivers and transmitters. Although there are many kinds of electronic and high frequency oscillators, all of them adhere to a basic principle: using a sensitive amplifier so that the output is fed back to the input in phase resulting in the signal regenerating and sustaining itself.

The mobile phone networks of today use different frequency bands below 3 GHz which can provide the best coverage over large areas. However, bandwidth is limited to 20 MHz per mobile operator. An assessment by the World Radio Congress found that frequencies above 24 MHz can provide the greatest bandwidth and it will be an area where 5G can deliver the highest data rates.

5G may be years away from being launched but a lot of manufacturers are already making components available that are capable of supporting the technology.
