Insulation Resistance
Follow instructions supplied with the motor insulation tester. The insulation resistance value will vary depending on
the temperature, humidity, extent of contamination, the servicing period, test running time, as well as the motor out-
put, voltage and type of insulation. Therefore, the insulation resistance (r) cannot be expressed uniformly; however, it
should be equal to or greater than the value listed in
Table 7
