The Tap Changer Analyzer & Winding Ohmmeter RMO60TD instrument is designed for winding resistance measurement of inductive objects, and for a tap changer analysis. The RMO60TD instrument is based on the state of the art technology, using the most advanced switch mode technology available today. The RMO60TD instrument is accurate (0,1%), powerful (up to 60 A) and lightweight. It generates a true DC ripple free current with automatically regulated measurement and discharging circuit.

The RMO60TD instrument can perform a simple, quick and reliable transformer on-load tap changer condition assessment. This instrument enables 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.
