Key Features

  • Ergonomic design ensures ease of use, hence subsequent reduction in instrument learning time. This allows the operator to undertake accurate safety testing in a minimum amount of time.
  • Fast charging of high-capacitance samples reduces testing times.
  • Current guard circuit ensures highly accurate measurements and test results, thus avoiding external interferences that could affect the accuracy of any test results.
  • Highly accurate voltage and current outputs normally associated with a test bench or laboratory test set, in a rugged, field-proven case, takes high accuracy into the field environment.
  • User selectable current trip points provide protection to the test piece and the operator in the event of a breakdown in the insulation of the object being tested.
  • Adjustable ionization indicator gives audible indication of electrical discharges during test.
  • Universal input 85-264 V ac, 47-440 Hz makes the MIT30 suitable for a wide variety of applications.
  • Compact, lightweight and rugged construction makes the unit ideal for field use.
  • Its rugged, field-proven case has in integrated carry handle for easy carrying and an air transport pressure relief value which allows the instrument to be safely transported without damage.

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 is NOT suitable for use on grounded/earthed test samples.

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 MIT30 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.

Applications

The MIT30 checks the electrical insulation quality and integrity of a wide variety of insulation material on UST ungrounded systems.

Due to the unique combination of up to 30-kV high voltage, high accuracy down to 100 nA, and low current 0-330 µA, the MIT30 has several applications:

  • Acceptance and Maintenance Testing of Electrical Plant:
    • Switchgear
    • Buss-Bars
    • Capacitors
  • Defense Industry
  • Aerospace Industry
  • Rubber Safety Glove Testing
  • Testing of Vacuum Interrupters
  • Power Equipment/Plant Manufacturers to Perform QA/QC Production Tests


What's included with the Megger MIT30

  • HV Triaxial Output Cable, 3 m
  • Input Power Cord, 120 V
  • Input Power Cord, 230 V
