The DV Power RMO60TC is designed for resistor type on-load tap changer analysis and resistance measurement of inductive test objects. It generates true DC ripple free current and both the injection of current and discharge of energy from the inductance are automatically regulated. Two independent channels enable testing of two series windings, or primary and secondary windings. There is enough memory within RMO60TC to store 500 measurements, all of which are time and date stamped.
Features
The DV Power RMO60TC Winding Ohmmeter can inject 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. It is equipped with thermal and overcurrent protection and has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. Using the DV-Win software, tests can be performed from a PC with the results sent directly to the PC. Using DV-Win and the RMO60TC it is possible to perform heat run test on distribution and power transformers. The RMO60TC can be used to measure winding resistance of individual taps of a power transformer’s tap changer and can also check whether the on-load tap changer (OLTC) switches without an interruption.
