As per Indian Standards, they must be seperately grounded
into different Earth pits.

Answer / dayal varma

to make standby if neutral fail then the device get the
neutral from the earthing.

Answer / yogesh

If neutral earthing pit is separate & body earthing is
separate & if there is body earth fault voltage will develop
at the body suppose 230 V & someone touches body & neutral
potential difference will be 230 V & person will get shock.

If both pits are interconnected same potential will be there
& PD will be zero. So no shock.

For polarity test on a 11/3.3kV 2.5MVA delta-star Unit Auxiliary transformer,415V 3-phase supply was applied at the HV. Connection between Aa was made with a 2.5mm cable. As soon as power was switched on the cable caught fire and burnt. This test was then abandoned. It is noteworthy to say that a similar cable was also used in a similar transformer for the same. The cable did not burn and test was successfully completed with good result. What is wrong? Please, help me out.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
