Megger MiT30 30 KV DC Hipot Tester


Overview

 Specifically designed for ungrounded test samples only

  •  Continuously variable test voltage, 0 – 30 kV
  •  Test current 0 - 330 µA
  •  Output voltage accuracy, + 1.5% (full scale)
  •  Built-in adjustable ionization indicator
  •  Fail-safe grounding and ¡°zero-start¡± switches
  •   Rugged, compact, lightweight, and portable
  • 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 (¡¾1.5%). 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.


    DESCRIPTION

    The Megger MIT30 is a portable 30-kV insulation tester that has been developed to satisfy the demand for a variety of high voltage, high accuracy, low current applications. The MIT30 is used to perform HV insulation tests (proof/ hi-pot test) on insulating material where low levels of leakage current, down to an accuracy of 100 nA, need to be measured. The MIT30 has a test current of up to 330 ¥ìA, and userselectable trip levels from 0 to 360 ¥ìA. 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.

    FEATURES AND BENEFITS



    • 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.n 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.n 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 unit offers unparallel accuracy and resolution, with a high voltage output from 0 to 30 kV dc., trip levels from 0 - 360 ¥ìA and a resolution of 1 nA (¡¾1.5%). The MIT30 represents excellent precision in a field instrument, and gives the operator confidence in the meaningful results.


    Safety and Reliability



    • Fail-Safe, gravitationally invariant internal grounding switch

    • Zero-Start safety provisionn 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
