  • RMO20TW - Winding Ohmmeter The Winding Ohmmeter RMO20TW is designed for the resistance measurement of inductive test objects and for on-load tap changer verification. The RMO20TW generates a true DC ripple-free current. The injection of current and discharge of energy from the inductance are both automatically regulated. The two independent channels enable testing of two windings in series. The RMO20TW has a very high ability to cancel electrostatic and electromagnetic interferences that exist in the HV electric fields. An automatic connections check is performed at the beginning of each test, and the instrument warns the user if an open connection is detected.
