A complete portfolio of solutions

For the last 30 years, we have worked with our clients to understand and provide solutions to improve the reliability of their electrical supply. 

The electricity landscape is changing. Maintaining a functional production line is more difficult than in the past.

Some of the factors that are diminishing the quality of your electricity supply include:

  • Climate change increases weather-related electrical faults
  • Electric vehicles and renewable energy integration influence grid stability
  • Sophisticated electronics in equipment are more prone to malfunction, overheating or failure if the electricity supply is of poor quality

Our portfolio of solutions includes the full spectrum of correction equipment to solve these problems.

Using our Omniverter toolkit gives an overview of our product solutions.

Active Voltage Conditioner (AVC)

Active Voltage Conditioner - AVC

The Omniverter Active Voltage Conditioner corrects voltage sags. Voltage sags are one of the main power quality problems that result in unplanned process stoppages and equipment failures.   

These sags are usually weather-related and not in the control of the utility operator. Causes of voltage sags include lightning storms, tree branches touching electrical wires, animals, or motor accidents coming in contact with electrical wires. Voltage sags can also be caused by starting of large motors, transformer energizing, and overloads. 

A voltage sag is a reduction in RMS voltage, between 10% to 90% of the nominal voltage for between 0.5 – 30 cycles. In North America, a voltage sag is defined by the remaining voltage as a % of nominal. In Europe, a voltage dip is defined as the % drop in voltage from nominal.

The AVC  provides ultra-fast and accurate voltage compensation by correcting the phase angle and the voltage magnitude in less than 3ms. Besides sag correction, the AVC provides continuous voltage regulation, corrects voltage unbalance, and reduces short-term flicker.

The AVC is the recommended solution for industrial applications that experience unplanned production stoppages due to upstream voltage sags.

Industrial UPS

Industrial UPS with Ride-through Protection - AVCRTS

The AVCRTS is an industrial UPS designed to provide stable power during momentary power interruptions.

Momentary outages are typically found when customers are fed at medium voltage by the utility. These outages occur due to recloser and switching operations. As a result, a shortpower outage can last anywhere from a few milliseconds to a few seconds.  

Common causes of recloser operations include faults occurring during lightning storms, fallen tree branches, or animals coming in contact with power lines and vehicle accidents taking down poles.  

The AVCRTS also corrects deep voltage sags and provides short-term outage protection. Due to its ultrafast IGBT technology, the transfer time is less than ¼ of a cycle.

The modular inverter construction (standard with N+1) and robust fail-safe bypass provide the highest efficiency and system availability.

The system has a very low source impedance with a high fault rating to operate in harsh industrial environments.

Active Harmonic Filter

Active Harmonic Filter - AHF

The Omniverter AHF is used to correct voltage and current harmonics generated at the source inside a facility.

Modern electronic equipment generates a variety of harmonic frequencies, which can distort the quality of your electricity. This distortion is caused either upstream or downstream in your electrical network.

The consequences of high harmonic distortion include capacitor failures, nuisance tripping, increased heat in conductors and motor windings, and faster-bearing degradation.

The AHF reduces the Total Harmonic Distortion (THD) to acceptable limits.

An additional advantage of the Omniverter AHF is the option to configure the filter as a 4-wire system. With a 4-wire system, it is possible to filter triplen harmonic frequencies. For example, the 3rd order harmonic causes a sharp increase in the current and flattens the top of the voltage wave. This reduces the ride-though capability of switch-mode power supplies and increases additional heat to the neutral conductors.

Dynamic Harmonic Filter from Omniverter

Dynamic Harmonic Filter - DHF

The Omniverter Dynamic Harmonic Filter corrects harmonics generated at the source within the facility and harmonics generated elsewhere that is transmitted into the facility via the electrical utility supply.

The DHF is an active-controlled filter. It uses a microcontroller, fixed inductor, and adjustable capacitors to trap specific low-order harmonics. The DHF Smart Sensing control allows for automatic impedance regulation and responds instantly to variations in loads.

The range consists of three interconnected modules. The DHF will correct 5th, 7th  and 11th harmonic created by loads within the customer's premises and from those generated elsewhere and transmitted via the electrical utility supply.

Dynamic Harmonic Filter

Resonance Elimination Filter

Resonant conditions occur as the electrical grid expands and additional non-linear loads and energy sources connect to the network. Depending on the response of the electrical network, electrical resonance may result in damaging overvoltage or overcurrent conditions.

The REHF is a high-pass filter that combines a resistor with an inductor and capacitor to correct resonance at higher frequencies. The resistors in the circuit dissipate the unwanted energy  and reduce specific resonant condition.

The REHF is used when disturbances or resonances occur at high frequencies or to eliminate the effect of utility capacitor switching transients.

Larger size REHF systems are available to reduce the impact of commutation notches through high-power converters.

Power Quality GRIDVIS Analysis

Jantiza Analyzer Range

Visibility is the first step in protecting your equipment. Omniverter offers a range of energy and power quality analyzers and software.

The UMG 509-PRO network analyser is a multi-purpose unit that continuously monitors the power quality and analyses electrical disturbances in the event of network problems.

The UMG 512-PRO is a class A certified power quality analyser per IEC 61000-4-30. Power quality parameters such as harmonics up to the 63rd harmonic, flicker, short-term interruptions, etc., are measured per class A.

SEMI F47 Voltage Sag Generator

Voltage Sag Generator & Simulator

Omniverter Voltage Sag Generator (VSG) units are designed to create controlled voltage sags.

The VSG is used as diagnostic tools for industries and electrical utilities who wish to conduct voltage sag testing to determine whether equipment complies with standards such as SEMIF 47-0706 and IEC 61000-4-34.

The Omniverter VSG’s are based on original technology developed by EPRI over many years. The data acquisition systems will monitor and record the response of the equipment under test.

Automatic Voltage Regulator

Automatic Voltage Regulator - DIGIT@L

In many parts of the world, electrical power quality is poor or inconsistent. As a result, voltages magnitude can vary significantly from nominal values, typically +15%/-20% or more, sometimes for several hours at a time.

The IEC describes these voltage fluctuations as cyclical variations of the voltage envelope or a series of random voltage changes of up to ±10% of the nominal voltage. These variations in voltage are also called voltage brownouts and swells.  

Long-duration brownouts and swells can cause electronic equipment to malfunction and degrade over time. The leading causes of voltage magnitude problems include inadequate utility services, long rural electrical lines, or heavy draw of electrical loads connected to a weak electrical grid. 

The DIGIT@L was developed for these conditions and is mainly used in emerging markets. The Omniverter DIGIT@L compensates for brownouts and swells. In addition, it improves the voltage stability of feeding loads by providing continuous voltage regulation.

Reactive Power Compensation

Power Flow Controller - PFC LITE

Reactive power plays a vital role in maintaining a stable voltage. Injecting reactive power into the system raises the voltage and absorbing reactive power lowers the voltage.    

Loads like induction motors, fans, pumps, or transformers require sufficient reactive power to start. When there is insufficient reactive power available, the voltage drops. It is then impossible to push the power demanded by the loads through the line.  

The Omniverter PFC LITE provides dynamic VAR support and correction in the case of applications where the motor starts cause deep voltage sags in the electrical network.

The PFC LITE is ideal for industrial applications to correct load-generated sags, but can also be used for dynamic power factor correction.
