Winding Ohmmeter & Tap Changer Test Set – RMO25T

The Winding Ohmmeter & Tap Changer Test Set RMO25T is designed for resistance measurement of inductive test objects. RMO25T generates true DC ripple free current. Both injection of current and discharge of energy from the inductance are automatically regulated.
RMO25T injects current with a voltage as high as 60 V. This ensures that the duration of test is as short as possible, and that the desired test current is reached faster. Two independent channels enable testing of two series windings, or primary and secondary windings. There is enough memory within RMO25T instrument to store 500 measurements. All measurements are time and date stamped.
The set is equipped with thermal and overcurrent protection. The RMO25T has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing appropriate hardware and software.
