RMO-TW, TD and TT Series
RMO-T instruments can perform a simple, quick and reliable transformer on-load tap changer condition assessment. These instruments enable measurements of a winding resistance in every tap position, current ripple values (percentage of a current drop during a tap change) and transition times during the tap changes. Problems with a connection, contacts, and selector/diverter switch operation (tap change with interruption) can be detected with these measurements.
Typical application areas of the RMO-T are high-voltage substations and industrial environments. They are intended to measure the resistance of:
Two-channel winding resistance measurement, and tap changer verification.
RMO-TD series has all the RMO-TW features and also tap changer analysis (DRM), OLTC motor current measurement and demagnetization process.
RMO-TT series has all the RMO-TD features including additional third voltage measurement channel and 3/6 temperature measurement channels.
