Product Introduction

DF3000 is mainly used for AC induced overvoltage withstand tests on 35KV-220KV voltage transformers, assessing the graded insulation level of 35KV-220KV voltage transformers. It is suitable for AC withstand voltage tests on 10KV~220KV cables; power frequency withstand voltage tests on large transformers and generators; AC withstand voltage tests on 110KV and 220KV GIS systems; and AC withstand voltage tests on 110KV and 220KV high-voltage switches, PTs, and CTs.
