typically this can be done using a high potential device
that applies a high voltage signal to open circuited
conductors. The meter on the device measure the micro-amps
of leakage through the insulation of the cables.

We can check earth leakage by a instrument Its name is Magger.

calculate external resistance values to add to the rotor of a slip ring induction motor. STATOR- 415 V, 3 phase delta, 1100 A, 50 Hz, 1490 rpm, pf 0,86 ROTOR - 660 V, 590 A, 50 Hz. STATOR current at each steps STEP1-600A,STEP2- 800A,STEP3-1000A,STEP4-1100A.
