MODULAR TEST SYSTEM (AC, DC AND IMPULSE)

The modular test system is based on portable and light elements which can constitute suitable circuits to provide AC, DC, and impulse voltages. For example a DC test system is based on an AC voltage transformer which charges HV capacitors with a DC voltage through HV diodes and resistors. These systems provide high DC voltages to test HVDC facilities, long AC cables, capacitors and so on
