WebSep 7, 2024 · Mho relay is a voltage restrained directional relay. Reactance relay is suitable for the protection of a short transmission line because its operation is independent of arc resistance. The relay which is selected for a long transmission line should be less affected due to power swings. Hence Mho relay is preferred. WebThis approximation can be used to provide a rough estimate of the expected distance relay to the arc resistance in a fault. The radial line of Figure 1, response of a assuming a 500KV system with a PT ratio of 4343:1 , was used to calculate the voltage at the relay location and the drop in the line for various source to line impedance ratios. streaming horreur vf
