GIS pipes for Ultra High Voltage

GIS pipes for Ultra High Voltage

The WRM AC resonant test systems with variable inductance are used for factory testing of high and ultra-high voltage cables, power transformers, and gas-insulated switchgears.They use the resonance between the capacitive test object and the inductive HV reactor of the test system to generate a continuous sinusoidal high voltage.
