The Three-Phase Winding Ohmmeter TWA25A is designed for six-winding resistance measurement of both the primary and the secondary transformer windings. This is performed with a one single-step cable setup, with test currents of up to 25 A. Each transformer configuration has a special measurement algorithm which is optimized for the fast stabilization of test results.
