UHV-20A Transformer DC Resistance Test Set-Catalog-2

Wuhan UHV Power Technology Co.,Ltd. DC resistance measurement of transformer winding is an essential test project during transformer delivery, repair and changing tapping switch. Usually, it is a time consuming task to use traditional methods (bridge method and voltage drop method) to measure transformer winding and DC resistance of high-power inductive device. In order to change this situation: shorten measurement time and reduce the staff ’ s workflow, our company has developed DC resistance rapid tester. The instrument using new power technology, with characteristics such as stable performance,...
