How to check THREE PHASE INDUCTION motor winding resistance for new good motor

How to check THREE PHASE INDUCTION motor winding resistance for new motor what is megger? The Megger is the instrument uses for measuring the resistance of the insulation. It works on the principle of comparison, the resistance of the insulation is compared with the known value of resistance. If the resistance of the insulation is high, the pointer of the moving coil deflects towards the infinity, and if it is low, then the pointer indicates zero resistance. The accuracy of the Megger is high as compared to other instruments. application: Accurately perform insulation testing on power MV and HV transformers, current transformers, cables, motors and generators (stators and rotors), circuit breakers, and more. Ensure continued operation of transmission and distribution equipment, preventing outages and downtime Maintain productivity even with a dead battery—operates from online mains power more videos what is mutimeter in tamil? https://www.youtube.com/watch?v=0Mb45wZ-U4g&t=207s how to check trasistor npn or pnp? https://www.youtube.com/watch?v=9RlSwrhoPqE&t=72s Selection of IR Testers (Megger): Insulation testers with test voltage of 500, 1000, 2500 and 5000 V are available. The recommended ratings of the insulation testers are given below: Voltage Level IR Tester 650V 500V DC 1.1KV 1KV DC 3.3KV 2.5KV DC 66Kv and Above 5KV DC
