Single-phase or polyphase synchronous motors can't start
without being driven, or having their rotor connected in
the form of a self-starting circuit. Since the field is
rotating at synchronous speed, the motor must be
accelerated before it can pull into synchronism.
Accelerating from zero speed requires slip until
synchronism is reached. Therefore, separate starting means
must be employed.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
