DV Power TWA40D Tap Changer & Winding Analyzer 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 singlestep cable setup, with test currents of up to 40A.
Each transformer configuration has a special measurement algorithm which is optimized for the fast stabilization of test results. The TWA40D generates a true DC ripple-free current. Both the injection of the current and the discharge of energy from the magnetic circuit are automatically regulated.
Standard set: instrument, ground cable, USB cable, software, tap changer
