Winding Resistance Meter

The WRT-10 is a high performance winding resistance tester designed for Power Transformer and large motor applications. Winding resistance testing is an important part of a power trans-former maintenance or a manufac-turing quality assurance program. Transformers & large motors are subject to vibrations, overloading and environments with large tem-perature variations. Winding resis-tance measurements can assure that the connections are made cor-rectly and that no opens or shorts are present. Tap changers of power transformers are a particu-larly critical element of a power system. The WRT is very effective in detecting Tap changer abnor-malities.
