Measurement Of Insulation Resistance Of Transformer at Michael Brenton blog

Measurement Of Insulation Resistance Of Transformer. The measurement of insulation resistance is a common routine test performed on all types of electrical wires and cables. A pi of less than 1 indicates equipment deterioration and the need for immediate maintenance. For example, a motor rated at 2,400 volts should have a. Insulation resistance testing, commonly known as the megger test, is an essential procedure for assessing the quality and reliability of electrical insulation in transformers. As a production test, this test is often used as a customer acceptance test, with minimum insulation resistance per unit length often specified by the customer. This test is performed at or above rated voltage to determine if there are low resistance paths to ground or between winding to winding as a. The general rule of thumb that is used for acceptable values for safe energization is 1 mω per 1000 v of applied test voltage plus 1 mω. The pi is the ratio of the insulation resistance at 10 min to the insulation resistance at 1 min. Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. This test helps in detecting insulation deterioration that could eventually lead to transformer failures.
