Mit30 30 kv dc insulation resistance tester
the megger mit30 30 kv dc insulation resistance tester is portable, 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 has a test current of up to 330 μa, and user selectable 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. An audible ionization indicator gives an audio indication if any electrical discharges present during the test period.
The mit30 can be used to perform step-voltage and proof tests which, when incorporated into a routine maintenance program, can aid in predicting potential failure before breakdown occurs.
The mit30 will operate from a wide range of input voltages and frequencies, from 85-264 vac, with a frequency range of 47-440 hz
