Detuned Filter Reactors
ENT.ERH Series
Summary

ENTES tuned filter reactor is designed for reactive power compensation system, which can compensate capacitors by suppressing harmonics and reduce harmonics in the system.
Harmonic filter reactor is used in series with capacitor in reactive power compensation system. The harmful effects of the system can be avoided by using the harmonic filter reactor. When using the harmonic filter reactor, the current flowing into the capacitor can be reduced by adding additional impedance to the capacitor.
So:
When the capacitor is put into operation, the harmonic current flowing through the capacitor is reduced and the capacitor is kept at low temperature.
Avoid high current when capacitors are put in.
Eliminate the overload risk that resonance may bring.
Therefore, due to the reduction of the probability of heating and insulation faults, the service life of capacitors can be prolonged. On the other hand, due to the reduction of harmonics in the equipment, sensitive equipment such as computers, medical devices, PLC will reduce the distortion effect caused by harmonics.
Technical characteristics:
Air gap design to minimize shell grounding resistance
High quality copper or aluminium winding, high permeability iron core
Complying with EN61000-2-2 anti-harmonic load design standard
Intermediate coil thermal protection switch to prevent equipment overload and overheating
Vacuum dipping process with low noise, minimizing heat loss and high mechanical properties
CE certification and compliance with EN 61558 2-20
