Hvac Megger Insulation Resistance Test For 3 Phase Motor Windings Touch test probe to shunted compressor terminals. depress test button on test probe (or on meter) for test duration period (60 seconds). record resistance value and terminal temperature. remove shunt across compressor terminals and restore to proper electrical connections. place compressor in operation for 5 or 10 minutes. Hvac(heating, ventilation, air conditioning) megger insulation resistance test for 3 phase motor(windings insulation resistance)supco m500 megohmmeter check.
How To Test 3 Phase Motor Using Megger Winding Resistance And To assess the insulation quality, a megger tests a wire by exposing it to a high dc voltage for a predetermined time. in general, the process of testing a 3 phase motor with a megger is easy: turn off the motor’s power source by flipping the circuit breaker. set the megger to ohms and then check the leads to check electrical continuity. How to perform a motor winding resistance test. using a multimeter check the resistance between the three terminals. these terminals are u, v, and w. multimeter to test for resistance (ohms) in three phase motors, the readings between each winding should be around the same. each of the three windings is identical and the resistance should be. In this video you will find out how to test 3 phase induction motor. for tests we'll use megger mit 310. we'll learn how to identify windings, check winding. Shunted compressor terminals. 10. initiate test: depress the test button on the probe (or meter) for a duration of 60 seconds. 11. record data: record the resistance value and terminal temperature. 12. restore connections: remove the shunt across compressor terminals and restore electrical connections. 13.
