The Tap Changer & Winding Analyzer
TWA40D is designed for six-winding resistance measurement and simultaneous three-phase on-load tap changer analysis 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 40 A. Each transformer configuration has a special measurement algorithm which is optimized for the fast stabilization of test results.
