All this with Carrier Receive then the relay will send an Echo and weak in feed Local Trip after the time of Address No: ( 2502A ) But if the one phase voltage is more than the Address No: ( 2505 ) the relay will send Echo Only after time of Address No: ( 2502A ) : Trip / Echo Delay After Carrier Receipt. = 5 Sec.

( i ) If the changing of the Impedance in the Polygon is slowly ,

then the relay will be Blocked by The Power Swing Function. ( ii ) If the changing of the Impedance in the Polygon is fastly and the Impedance is go out from the Polygon , then any Fault will make Trip.
