Leakage Current Test of Motors and Electrical Machine

leakage current should be negligibly small so that there is no risk to the operator and operator and machine is safeguarded. The limit for the current so measured by the external circuitry shown in the diagram shall not be more than 2.5 mA



Procedure:

  • The motor is applied with a voltage 1.1 x rated voltage through auto transformer.
  • An external circuit consisting of a mili ammeter and a resistance R = 2000± 50 value is connected as shown in the diagram. For the perfect condition of the insulation of the motor, the mili ammeter reading should not exceed 2.5 mA
