Answer Posted / dr. s.r.krishnamurthy
If a fault occurs at say 98%th portion of generator phase
winding reconed from the phase terminal, the voltage
induced in that balance 2% winding is not sufficient to
drinve a fault current through the differential relay.
Hence intentionally 100% protection relay is not used.
