RMO-TW Winding Ohmmeter

RMO-TW Winding Ohmmeter
Product introduction

RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.

▪ Three resistance measurement channels
▪ One temperature measurement channel
▪ Accuracy (0,1% rdg + 0,1% F.S.)
▪ Lightweight
▪ On-load tap changer verification
▪ Automatic resistance measurement for the Heat Run test
▪ Rapid automatic demagnetization
▪ Automatic discharge circuit
▪ Resistance measurement of transformers, rotary machines and non-inductive objects
▪ Four models: RMO10TW, RMO20TW, RMO30TW, RMO50TW
The list of the instrument application includes:
▪ Three-channel winding resistance measurement, which enables simultaneous winding resistance measurement of up to three windings on a single phase
▪ Detection of interruptions during the operation of on-load tap changers (OLTC), performed on a single phase
▪ Heat Run test, which enables obtaining the Hot Spot temperature along with resistance graph during the cooling process
