Product Description
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.

1.Controlled by single chip, easy to use
2.Full protection, can prevent from counter electromotive force
3 with audio discharge alarm and discharge indicating function
4. Fast response time, can swtich on load tap changer when measuring.
5. Intelligent power management,
6.With micro-printer, can print test results.
