Distance Relay In Transmission Line. They provide selective protection to. this type of relays are most widely used where there is a need for fault protection, backup protection in transmission and distribution lines at high speeds, and also when the overcurrent relaying is very slow. when the transmission line’s impedance has a direct relation to the length, then it can be easily stated that distance relay only functions when defect takes place within the specified line length or distance. the admittance relay is the most commonly used distance relay. distance relays play a critical role in ensuring the reliability and stability of modern power systems. An impedance relay, also known as a distance relay, is defined as a device that triggers based on the electrical impedance measured from a fault’s location to the relay. the basic principle of distance relay is that the apparent impedance seen by the relay, which is defined as the ratio of phase voltage to line current of a transmission line (z app), reduces drastically in the presence of a line fault. This article helps to know about the distance relay and its types in detail. It is the tripping relay in pilot schemes and as the backup relay in step.
