Megger has the provision to directly read the insulation resistance during insulation resistance test.

Insulation resistance test transformer.

Time resistance testing method this method is fairly independent of temperature and often. All insulators are supposed to be pure capacitor having very few capacitance so as to take minimum charging current. 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. Insulation resistance test of transformer.

Insulation resistance test between windings. The insulation resistance test is the second test required by the electrical safety testing standards. A 500v insulation resistance test is suitable for 110 400 volt transformers. The minimum insulation resistance value accepted in each of the above tests is 2m.

The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together. Isolation required for the test. Leakage current should be as small as possible therby ir value should be as high as possible r v i. The insulation resistance test of the transformer is one of the most important transformer tests we can perform this test at a factory or site this test can be classified under type test routine test pre commissioning and commissioning tests periodic maintenance transformer tests.

Insulation resistance is the ratio of the applied voltage dc to the total leakage current. Megger insulation resistance test device.
