Principle Of Distance Relay at Tina Diane blog

Principle Of Distance Relay. Distance relays respond to the voltage and current, i.e., the impedance, at the relay location. The distance relay principle can be explained in two conditions: The impedance per mile is fairly constant so these relays respond to the distance between the relay location and the fault location. The basic principle of distance protection involves the division of the voltage at the relaying point by the measured current. Since the impedance of a transmission line is proportional to its length, for distance. The apparent impedance so calculated is compared with the reach point impedance. Unlike other relays whose operation depends upon the magnitude of current or voltage, the principle of distance relays is different. So, the relay will not function. Therefore, deflecting torque > restoring torque. The mho function uses the current and voltage measured at the relay to determine if the apparent impedance plots within the mho characteristic.
