Filter Reactor/Detuned Reactor

Filter circuit chokes protect reactive current compensation systems from overloads caused by interference levels in medium and low-voltage networks.

MANGOLDT filter circuit chokes are available for low voltages and medium voltages as single-phase or three-phase iron core chokes for detuned and tuned filter circuits. Depending on requirements and environmental conditions, the design is adapted to all customer requirements – from the winding of the coils with copper wire, copper or aluminium tape to temperature monitoring. On request, a type test with heat run according to IEC 60076 under real conditions or a partial discharge test can be carried out.

Our filter circuit chokes also feature PolyGap® construction. This, together with a complex vacuum pressure impregnation process, ensures that noise emissions are minimised.

For use in North America, MANGOLDT filter circuit chokes are also available with the necessary test marks in accordance with UL guidelines.
