If you need to extend the load capacity of your existing AC test system, PCR is the solution.
Suitable for long-term testing of high-capacitive test objects like power cables, capacitors or other capacitve test objects.
Mohaupt PCR are turn-key solutions designed on request and optimized according to your available feeder system.
Mohaupt Parallel Compensation Reactors (PCR) allow to substantially extend the capacity of your existing AC test system, whether it is a conventional test transformer or resonant test systems.

The key to expand the load capacity as much as possible without modification of the existing feeder system is, to use reactors of low loss design. Conventional reactors do have an iron core. The iron core generates additional losses in addition to the copper losses of the wire. This drawback is overcome by MHVs ironless design. The reactors consist of “air” windings (even though oil insulated). These windings provide excellent electrical performance in steady state operation, as well as in transient conditions (flash over or breakdown of test objects). Furthermore, they have substantial better cooling performance compared to conventional reactor windings, enabling currents up to 84A per reactor without any thermal restriction and subsequent accelerated aging, due to thermal heating of the insulation.
