Answer / srinualn117

purpose of checking IR value is to find,the insulation
resistance between the phases of winding and with
respective to body also.
Minimum IR value required is for 2megaohms/1KV

Answer / deena

it is check for insulation of windiig between the ground

Answer / prasang

IR is tested to check the soundness of insulation resistance & freedom from earth leakage faults between phase to phase, phase to neutral, phase to earth and earth to neutral...
