what is the acceptable insulation resistance for motor/transformer?
Answer Posted / gajendra singh
Insulation resistance tests are made to determine insulation resistance from individual windings to ground or between individual windings. Insulation resistance tests are commonly measured directly in megohms or may be calculated from measurements of applied voltage and leakage current.
