Insulation Resistance Test On A 3 Phase Circuit Ptt Youtube This video shows a comprehensive demonstration of how to do insulation resistance test on a 3phase induction motor.the video includes everything you need to. We have had a number of requests for a method or sequence of testing for 3 phase installations. in this short video we will show just one method of a reliable and fool proof testing sequence that we have used for many years. This video explains how to check the ground insulation of an ac motor winding using the insulation resistance (ir) test. the ir test is usually the first electrical test because it indicates if the motor winding can withstand further testing, or the machine can return to service. this video shows: how to select the megohmmeter and ir test voltage how to connect the megohmmeter to the winding. How to perform an insulation resistance test. using an insulation resistance tester or megger, you should set the voltage to 500v. insulation resistance is measured between the phases of the motor and earth. check all phases to earth (u to earth, v to earth, and w to earth) after you have done this you should check phase to phase also (u to v.
