Helping to contribute to cleaner and more stable power

Power quality refers to the characteristics of the electrical power supplied to and consumed by devices. High-quality power ensures that equipment operates reliably, efficiently, and safely. Poor power quality can lead to malfunctions, reduced lifespan of equipment, and increased operational costs.

Key aspects of power quality include voltage stability, harmonics, power factor, voltage sags and swells, interruptions, transients and surges. Poor power quality  can be as a result of non-linear loads, industrial equipment with high, start-up currents, grid disturbances, faulty wiring or grounding.

EMC solutions provider EMIS announces the availability of the PQR-4 Series of Three Phase AC Line Reactor Power Quality Products. The PQR-4 series are designed to be used in Power Distribution (Line side of Drive) to provide input impedance which helps reduce harmonic distortion and increase VFD (variable frequency drive) component lifetime.

The EMIS  PQR-4 Series of Three-phase AC line reactors are essential inductive components installed in series with power lines in industrial and commercial electrical systems. They are primarily designed to enhance power quality and protect sensitive equipment.

Key features include:

• Reduced harmonic distortion caused by non-linear loads, such as variable frequency drives (VFDs) contributing to cleaner and stable power.
• They will limit voltage transients caused by utility switching or lightning strikes, safeguarding downstream components like inverters, motors, and drives from potential overvoltage damage.
• By introducing impedance into a circuit, they limit inrush current during short circuit events preventing nuisance tripping of circuit breakers and extend the life of power components.
• Additionally, they improve the quality of current waveforms by reducing peak currents. This leads to more efficient energy use and reduces thermal stress on components thereby increasing life span and improving reliability of drive systems.

The EMIS  PQR-4 Series may be used in applications such as variable Frequency Drives, industrial plants and factories, process automation equipment, AC Power Systems, Elevator and escalator Drives, CNC Machines and Robotics, welding machines, cable winding machines and to enhance the reliability of UPS systems and power distribution units.
