The MIT30 is a 30 kV Insulation tester that has been developed to satisfy the demand for a variety of high voltage, high accuracy, low current applications in electrical distribution industries, aerospace and defense applications.
The MIT30 cannot be used on grounded/earthed test samples. Otherwise, the unit will be damaged.
The unit offers unparallel accuracy and resolution, with a high voltage output from 0 to 30 kV dc., trip levels from 0 – 360 μA and a resolution of 1 nA (±1.5%). The MIT30 represents excellent precision in a field instrument, and gives the operator confidence in the meaningful results.
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.
