Answer / thran

motor value check from.... body to phase Then winding to winding phase came infinite using megger 1 kv r 500(dc volt megger came ohm value...

Answer / r.kumar

for megger test in motor.......we apply 500v DC supply at terminals and check:
1.phase 2 phase(ohms)
2.phase 2 body (>100MEGA OHMS OR GIGA OHMS)
3.phase 2 neutral(>1 GIGA OHMS)

Answer / bameshwar

To identify the motor winding is correct or not. Body to coil and coil to coil for identify the motors coils shorted or not. It's values are body to coil-infinity or more than 5megaohms,coil to coil - 0megaohms,and coil to othercoil-we are seeing the insulation between coils

Answer / bameshwar

To check the winding s of motor is correct or not (motor shorted or ready to run) it's values are body to coil-infinity, and the coil to coil - 0megaohms, & coil to other coil we are seeing insulation between coil to other coil which is according to motor.
