Description
The Megger MIT30 is a portable 30-kV insulation tester that has been developed to undertake tests on 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 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 of 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 Megger MIT30 insulation tester will operate from a wide range of input voltages and frequencies. The unit will will operate from 85-264 V ac with a frequency range of 47-440 Hz.
