   The new Megger MIT1020 10-kV insulation resistance testers are all designed specifically to assist the user with the testing and maintenance of high voltage equipment. The instruments are designed in a landscape style which is more familiar and user friendly. The MIT1020 offers a measurement range to 35 T½ in order to provide trending values for the best of insulating materials used on the higher capitalized equipment.


  • Line supply or battery operated
  • Digital/analog backlit display
  • Measurement range to 35 Teraohms
  • CAT IV 600 V safety rating
  • RS232 or USB download of results
  • Ingress protection to IP65
  • 3 mA short circuit current

   Redundant safety features make the instruments fully amenable to safe operation in the more demanding high voltage environment. The CAT IV 600 V safety rating means that the instruments are protected for use on outside applications and are protected against impulses to 8 kV. Instrument design is in conformance with EN61010 for arc-flash protection. If the instrument is accidentally connected to a live test item, external voltage will be automatically displayed and testing inhibited above 50 V. At the conclusion of a test, dangerous static voltage on the test item is automatically  discharged and monitored on the display. All three models are fitted with a guard terminal to enhance accuracy. The guard test lead is included as standard with each instrument.


   All Megger MIT1020 models are designed for testing the insulation of high-voltage electric equipment. Their wide voltage range also allows applications for low-voltage equipment. Generators, motors, transformers, cables and switchgear all require effective maintenance. The test techniques on the instruments provide valuable diagnostic information. All three instruments test the insulation resistance of:

  • High-voltage power cables and high-voltage buses
  • Large motor/generator windings
  • Line and substation transformers

   The Megger MIT1020 also perform spot tests, step-voltage tests, dielectric discharge tests and dielectric absorption tests for the following applications:

  • Acceptance testing at installation to check conformance to specifications.
  • Routine preventive/predictive maintenance testing after installation.
  • Quality assurance testing as part of the manufacturing process.
  • Diagnostic testing to isolate faulty components for repair.

   With its higher voltage testing capability, the Megger MIT1020 is the perfect every day work tool for manufacturers, users and maintainers of rotating machinery. Designed in accordance with the requirements of IEEE43:2000 the MIT1020 is ideal for measuring the insulation resistance of armature and field windings in rotating machines rated 1hp (750 W) or greater. The standard applies to synchronous, induction and dc machines as well as synchronous condensers.
