Distance Relays are of three types: ·         Impedance Relay ·         Reactance Relay ·         MHO Relay. Impedance Relay: As from Universal Relay Torque Equation, T = K1I2+K2V2+K3VICos(Ɵ-Ƭ)+K4 Where K1 = Constant             K2 = Constant             K3 = Constant             K4 = Spring Torque             V = Voltage fed to the Relay             I = Current … Read more
