Answer:
the national grid frquency for India is 50 Hz, but what happens, to the sychronous grid, is that during times of peak consumption, the frequency will drop to 49.9 or 49.8 Hz.
Is is during these times that motors and other devices that are dependant on the line frequency will loose some spin (motors) or slow down (clocks).
To balance this duration of peak demand, the electric company, during low demand, will boost the frequency to 50.1 or 50.2 hz for long enough as to get the national grid back to the ‘standard’ time.
