why neutral of 6.6 kv star connected sq. cage induction
motor does not get earthed, though for earth fault
protection it is must.
Answer Posted / venkatesh
the fundamental condition for connecting neutral to earth is that the neutral voltage should not be higher than supply potential .but in star connected squirrel cage induction motor the neutral potential was reached uplimit potential during starting.so, neutral was not connected to earth in that case while in transformers there is no problems of increased neutral potentials. though they were similar in some aspects
