Megger MIT30 Offers

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 ?A, and user selectable trip levels from 0 to 360 ?A. 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 ?A, 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

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.

Safety and Reliability

  • Fail-Safe, gravitationally invariant internal grounding switch
  • Zero-Start safety provision
  • Cable interlock with bright LED, visible even in direct sunlight
  • Triaxial HV output cable, with integrated HV, guard, and current sense
  • Detachable HV output cable, shielded with interlock provision
  • Output current overload relay
  • Switch control and indicating lights for high-voltage ON/OFF
  • Protected output for both short/open circuit conditions
  • Fused power inlet module
