Quick Details
Specifications
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/T16927.2(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
