A transmission line is protected by distance protection, time graded and current graded overcurrent protection.
Last Answer : The interaction between a transmission line and communication line is minimized by transposing transmission as well as communication lines, increasing the height of the transmission line tower, increasing the distance between the two lines.
Description : Transmission efficiency of a transmission line increases with the
Last Answer : Transmission efficiency of a transmission line increases with the increase in power factor and voltage
Last Answer : Reactance relay is preferred for phase fault on short transmission line.
Last Answer : When a wave propagates on a transmission line, it suffers reflection several times at sending and other end.
Last Answer : When a transmission line is energized, the wave that propagates on it is current wave and voltage wave.
