Voltage: 10kV - 2250kV (single unit YDTW up to 750kV, cascaded YDTCW up to 2250kV)

Current: 0.1A – 40A

The AC test transformers are especially designed for medium capacitance testing object, such as power transformers, cables, generators, motors, GIS switchgears, bushings and arresters. It’s particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet and pollution tests) or when the load is inductive (inductive voltage transformers).

The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space. We have successfully experienced 2250kV 4500kVA test transformer by three module cascaded.
