I think for single phase there is no need for earthing.
Earthing is useful to bypass the charge of thundering.
But incase of three phase generator we must use earthing
because, without earthing when loads are not equal among
the phases then the phase voltages are not same respect to
star point. Which is very dangerous for single phase user.

According to IEC60034-14, When the vibration monitoring system required for motor Bearing. above which KW, it is required? and for what type of bearing the vibration probe is provided.
