WebbThe relay would determine the impedance if it is in the reach setting of the relay. The impedance of the line will be proportional to the fault distance and that’s why it is called distance protection. This type of distance relay is for the medium-length transmission line.

Webb16 apr. 2024 · Relays can reduce the need for high-amperage wiring and switches, which are expensive and take up space. Therefore, switching to relays in your electronic systems can reduce the size or weight of a … Webbthe impedance seen by the relay will be dependent solely upon the source impedance. (The dependency on source impedance might be counter-intuitive to engineers accustomed to setting impedance relays in terms of line impedances.) The angle of Z 0,Relay and Z 2,Relay is the source of determining the direction to a fault. Webb23 nov. 2024 · Protection Relay – ANSI Standards.
