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, rapid test, small size, light weight, easy operation, high measure precision and good data reproducibility, is the ideal equipment to measure transformer winding and DC resistance of high-power inductive device.

product names：Dc resistance velocity tester, transformer DC resistance tester, transformer winding DC resistance tester, transformer direct resistance velocity tester, transformer direct resistance rapid tester, inductive load DC resistance velocity tester, inductive load DC resistance rapid tester, inductive load DC resistance tester.
