  • Product Introduction

ZC-205C Three-phase DC resistance tester is optimized designed to test  three-phase winding DC resistance of large-capacity transformer, is the latest generation of transformer DC resistance tester. ZC-205C can test the three-phase winding DC resistance of the transformer at the same time, adjust the tap-changer directly, no discharging is required for the on-load tap-changing transformer. The test time is one third of the traditional single-phase test, which can greatly shorten the working time and labor intensity.
