railway DFCCIL Junior Executive 2023 (CBT 1 & CBT 2) Mock Test Power Systems Transmission and Distribution
Which of the following statements is NOT true about AC power transmission?
1
AC line has capacitance. Therefore, there is a continuous loss of power due to charging current even when the line is open.
2
Due to skin effect in the AC system, the effective resistance of the line is increased.
3
The AC voltage can be stepped up or stepped down by transformers with ease and efficiency. This permits to transmit power at high voltages and distribute it at safe potentials.
4
The construction of an AC transmission line is less complicated than that of a DC transmission line.
