In this video we demonstrate how to test a voltage transformer using Megger's MRCT Relay and Current Transformer Test Set and the Instrument Transformer Management Software (ITMS). This software is used to configure and run the MRCT test set from Megger.
The Megger MRCT is a light weight, robust, portable unit used to perform demagnetization, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers. The MRCT automatically calculates ratio errors, saturation curves, and knee points. The MRCT provides a microprocessor-controlled variable voltage and current output and precision instrumentation for automatically testing single and multi ratio CTs, reducing testing time and increasing productivity. The MRCT will directly connect to multi ratio CT’s and perform all tests - saturation, ratio and polarity, winding resistance and insulation - on all taps with the push of a button and without changing leads. The integrated single phase relay test system allows the ability to test protection relays.
