Answer Posted / arun
distance relay used in transmission lines
T=k1 i2+k2 v2+k3 v *i*cos(thita -del)+k4
this is universal torque equetion use for defining distance relay
there r 3 types of distance relay mho relay used for long transmission lines for which k1 =0
reactance relay used for short transmission line for which k2=0
impedance relay used for medium transmission lines for which k3 =0
when evar impedance seen by the relay is less than reach then these relays operates means Zseen is less than Zset
