insulation resistance of motor windings
insulation resistance of motor windings
(OP)
In carrying out insulation resistance tests on three phase motors, is it possible for the resistance to earth to increase as well as decrease over time? Although over sufficient time it will decrease as the insulation breaks down.

Any degradation, either by time, environment etc will cause the insulation properties to reduce.
