The MIT1020/2 insulation resistance tester is designed specifically to assist the user with the testing and maintenance of high voltage equipment. The instrument is designed in a user-friendly landscape style.
The MIT1020/2 offers a measurement range to 35 TΩ in order to provide trending values for the best of insulating materials used on the higher capitalized equipment. The model features an expanded test voltage range from 50 V to 10 kV, in 10 V increments to 1 kV and 25 V increments above. The MIT1020/2 is supplied with two sets of test leads, one with medium insulated clips and the other with large insulated clips.
The instrument has a large, easy-to-read backlit LCD making them equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time is displayed constantly, removing the need for separate timers. The MIT1020/2 allows up to 3 timed measurement positions to be set, which simplifies DAR testing.
A built-in integral timer starts automatically at the beginning of a test, and displays in minutes and seconds. At the end of any test, capacitive loads are automatically discharged and the decaying voltage displayed. The MIT1020/2 has the capability of preprogrammed DAR, PI, SV and DD. The unit includes a selectable breakdown or burn mode and an alarm mode, which allows the operator to preset a specific resistance level. The unit will beep until the limit is exceeded. The controls of the instruments are clear and unambiguous, and a "quick start" guide is included in the lid, eliminating the need to carry manuals to site locations.
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 80 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.
The MIT1020/2 is designed for testing the insulation of high-voltage electric equipment. It's 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. It tests the insulation resistance of:
The MIT1020/2 also performs spot tests, step-voltage tests, dielectric discharge tests and dielectric absorption tests for the following applications:
