RMO100TT Tap Changer Analyser and Winding Ohmmeter by DV Power

The RMO-TT Series of Tap Changer Analysers and Winding Ohmmeters are designed for winding resistance measurements of inductive objects and tap changer analysis. These instruments can perform a simple, quick and reliable transformer on-load tap changer condition assessment. They 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 any connections, contacts, and selector/diverter switch operation (tap change with interruption) can be detected with these measurements. RMO-TT instruments provide temperature measurement for Heat Run tests by using four dedicated temperature channels. These enable hot spot temperature acquisition and the monitoring of the cooling process which is represented in temperature and resistance graphs.
