Application

DC voltage test system is widely applied in the DC withstanding voltage test and polarity change-over test of high voltage apparatus, such as high voltage transformers, surge arresters and cables and capacitors. The DC Voltage test system is designed for indoor use.

Standard

IEC60060-1, IEC60060-2, GB/T16927.1, GB/T16927.2

Advantages and Features

1. Free partial discharge, less than 200pC at  DC 1000kV output; less than 300pC at DC1300kV output;
2. Fast polarity reversal within 1 minute, polarity change-over time of SCR is less than 5 seconds;
3. Earthing system at the output terminal for safety;
4. With air cushion at the base for easy and smooth movement.
5. Automatic control & measurement system
