AC resonant test system with variable inductance, modular insulating case - WRM
- Modular high-voltage reactor units.
- Suitable for testing power cables and power transformers.
- Can be used in both parallel and series configurations.
- Voltage range: 250 - 1600 kV.
- Current range: Below 112 A.
- Power range: Below 56,000 kVA.
The WRM AC resonant test systems with variable inductance use the resonance between the capacitive test object and the inductive HV reactor of the test system to generate a continuous sinusoidal high voltage. The natural resonance frequency of the test circuit is matched to the feed-in frequency by setting the variable inductance of the HV reactor.
The modular concept with insulating case design enables you to connect the reactors in series or in parallel for extending the range of voltage and/or current.
