Series Resonant Test Systems with variable inductance and module type are used for factory testing of medium and high voltage cables, power transformers, bushings, high voltage capacitors, generators, arresters and high voltage accessories. They include stackable modules that can be used to test a wide range of products. The systems can be expandable to cover future test requirements that may require higher voltage and power levels.
AC resonant test system with variable inductance and metal tank type is used for factory testing of medium and high voltage cables, high voltage capacitors, generators, and motors. 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.
