The Megger MIT30 is a portable 30-kV insulation tester that has been developed to undertake tests on UST (ungrounded test samples). It satisfies the demand for a variety of high voltage, high accuracy, and low current applications. The MIT30 CANNOT be used on grounded/earthed test samples. Otherwise, the unit will be damaged. The MIT30 has a test current of up to 330 μA, and userselectable trip levels from 0 to 360 μA. The MIT30 provides protection to the test piece against flashovers (arcing) and further damage in the event of a breakdown.

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.
