The Winding Ohmmeter & Tap Changer Analyzer RMO40T is designed for resistance measurement of inductive test objects. RMO40T generates true DC ripple free current. Both injection of current and discharge of energy from the inductance are automatically regulated.
RMO40T 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 RMO40T instrument to store 500 measurements. All measurements are time and date stamped.
The set is equipped with thermal and overcurrent protection. The RMO40T 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.
