Answer ( 1 )

  1. 3 lead motor’s short circuit or inter-turn fault cannot be check using normal multimeter, but using RSO (Recurrence Surge Oscilloscope) detection technology we can easily find it.

    But we can find earth to winding healthy condition of the circuit using test lamp or megger.

    But My suggestion is go for test lamp, once the test lamp has passed then start motor trail with proper cooling. Then measure the submersible pump current. Now the three phase current is balance then, the motor is healthy, but if the motor current seems different then the motor will be faulty.
