How To Test Insulation Resistance Of A Transformer. The procedure for a megger test or insulation resistance test is as follows. Insulation resistance decreases in temperature or moisture.
Httpbitly2y9h9BSIn this video learn how to measure insulation resistance using the Fluke 1587 Digital Multimeter. Insulation Resistance or IR Test is carried out by maintenance engineers to ensure the healthiness of the overall insulation system of electrical equipment. AimPurpose of the IR Test.
To start the test simply turn the Fl.
Importance of transformer insulation resistance. With a little record-keeping and common sense however you can get a good picture of the insulation condition from values that are only relative. IR value will be usually high several hundred Megaohms for a dry insulation system. The temperature of the oil.
