MOEORW-W4610A26 Transformer DC resistance test

The MOEORW-W4610A26 DC resistance tester is a professional device for rapid DC resistance testing of transformers and other equipment, replacing single and double-arm bridges.

10A DC resistance tester features multiple current settings, a wide measurement range, high precision, temperature conversion, multiple data storage and transmission methods, comprehensive protection, and convenient operation.

It is suitable for DC resistance testing in the manufacturing, installation, handover, and preventive testing of electrical equipment such as transformers by the power sector.

Product Introduction

DC resistance measurement of transformers is a mandatory test item in the manufacturing process, including semi-finished and finished product factory tests, installation and commissioning tests, as well as preventive tests by the power sector. It can effectively detect manufacturing defects such as material selection, welding, loose connections, missing strands, and broken wires in transformer coils , as well as potential hidden dangers after operation. The DC resistance tester is a rapid testing device for measuring the DC resistance of transformers, instrument transformers , generators, and motors, and is a replacement product for single-arm and double-arm bridge circuits.
