Answer Posted / k.prakashchandra
Gen side means usually 11 KV.The generator current at full
load will be very high for 60 MW( 52.5 x MVA A)for an
indoor breaker .Therefore , synchronization and tripping on
fault are done at EHT breaker which is of above 110 KV.For
any fault between the breaker and gen ,the master trip is
employed ,which trips the field breaker ,CB and the governor.
