WRT-10D - Winding Resistance Tester with Demagnetisation Circuit

The WRT-10D is a high performance winding resistance tester designed for power transformer and large motor applications. It is equipped with a bright LCD display, a rugged high quality cable set, a built-in printer, a full QWERTY keypad and a demagnetisation circuit.

Winding resistance testing is an important part of power transformer maintenance or manufacturing quality assurance program. Transformers and large motors are subject to vibrations, overloading and environments with large temperature variations. With winding resistance measurements it can be determined if the connections are made correctly and that no opens of shorts are present. Tap changers of power transformers are particularly critical with several contacts and switches. The WRT-10D is very effective in detecting Tap changer abnormalities.
