Transformer winding resistance meters

The ATRM-20/3 and ATRM-40/3 are three phase transformer winding resistance meters that allow the user to connect all test cables to the transformer bushings. The unit will then measure the transformer resistance value for each of the phases without the need to disconnect and reconnect cables for each phase.

The QLTCA-40 is Amperis’ winding resistance meter and load tap changer contact analyzer. The QLTCA-40 is designed to accurately measure the winding resistance of highly inductive power transformers. The unit’s triple resistance reading input channels can measure three winding resistances simultaneously.

The QRM-10P is designed to accurately measure the winding resistance of highly inductive power transformers. The unit’s dual resistance-reading input channels can measure two winding resistances simultaneously, and four-wire (Kelvin) connections provide high accuracy and require no lead compensation.
