Insulation resistance test of transformer is divided into three parts. Excitation current test insulating fluid dielectric tests insulation pf test insulation resistance test ttr test. Values based on ieee std 43 2013.

Clean the terminals of the transformer. The test measures the insu lation resistance between the phases and or between phase and ground. Megger insulation resistance test device. A rated line to line voltage for three phase ac machines line to ground voltage for single phase machines and rated direct voltage for dc machines or field windings.

The transformer neutral bushing is to be disconnected from earth during the test. September 5 7 2018 1. Ansi neta mts 2015 table 100 11 insulation resistance test values rotating machinery for one minute at 40 c. Steps of this test.

The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Adjust megger tester at 1000 v dc. Use the megger test at a low voltage side. 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.

Pf 5 0 for dry type distribution transformers chl insulation pf tip up for dry type insulation should be 1 0 note. It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs. The following tests are routinely conducted in the field on the transformer. Insulation resistance testing is a non destructive test procedure.

This test can be repeated during the service life of the transformer and verified against the result obtained during manufacturing as a check to determine if the insulation is malfunctioning or decaying. Measure insulation resistance between low voltage windings and the main body of the transformer. Overall power factor and capacitance 2. The insulation resistance test is of value for future comparison and also for determining if the transformer is to be subjected to the applied voltage test the winding insulation resistance test is a dc high voltage test used to determine the dryness of winding insulation system the test measures the insulation resistance from individual windings to.
