Datasheet

The Megger MCT1605 test set is a lightweight, robust, portable unit used to automatically or manually perform saturation, ratio, polarity, demagnetizing tests and insulation tests on current transformers. The MCT provides a microprocessor controlled variable voltage output and precision instrumentation for automatically testing single and multi-ratio CTs. The MCT1605 possesses microprocessor controlled output voltage with precision instrumentation and storage, reducing testing time and increasing productivity. The MCT1605 will directly connect to multi ratio CT’s and perform all three tests – saturation, ratio and polarity – on all taps with the push of a button and without changing leads.

The MCT1605 will calculate the rated knee point in compliance with IEEE C57.13.1, IEC 60044-1 or IEC 60044-6
