Product Description

Brief introduction
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.


Products features

1. Small in volume, light in weight.

2. Easy to operate.

3. Fast test, test results accurate and stable

4. Can auto discharge and with discharge indicates function, to ensure the safety for equipment and people.

5. With micro-printer, can print test results.
