When a transmission line is energized, the wave that propagates on it is current wave and voltage wave.
Answer : When a wave propagates on a transmission line, it suffers reflection several times at sending and other end.
Answer : Reactance relay is preferred for phase fault on short transmission line.
Description : Transmission efficiency of a transmission line increases with the
Answer : Transmission efficiency of a transmission line increases with the increase in power factor and voltage
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.
Answer : A transmission line is protected by distance protection, time graded and current graded overcurrent protection.
