Megger MVCT test set is a lightweight, robust, portable unit capable of testing both current and voltage transformers. Capable of performing saturation, ratio, polarity, winding resistance, and insulation tests on current transformers, the MVCT can also be used for testing metering and protection class voltage/potential transformers. The MVCT provides a microprocessor controlled variable voltage and current output along with precision instrumentation for automatically testing single and multi-ratio CTs and VT’s. The MVCT makes testing CTs easy

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
