HOW DO A DISTANCE RELAY SENSES THE FAULTY ZONE. ..

Answer / d ramesh

Distances relay senses the faulty zone if impedance seen by
the relay is below the set value then it operates and
isolates the faulty zone.

z=v/i below the set, then operates
zone1= 80% of protected line
Zon2=100%protected line + 50%shortest line
Zon3= 100%protected line + 100% longest line.
