Which of the
following statements is not true with respect to ac transmission systems?
The power can
be generated at high voltages
Due to skin effect in the ac system, the effective resistance of the
line is decreased
The ac
voltage can be stepped up or stepped down by transformers with ease and
efficiency
The
maintenance of ac sub-stations is easy and inexpensive
Due to skin effect in the ac system, the effective resistance of the
line is decreased
A.C. power
can be generated at high voltage and it can be done with ease of step-up or
step-down voltage by the transformer. Also ac maintenance of distribution
sub-station is easy and cheap. In the AC system has a skin effect due to which
effective resistance of the line is increased, hence statement (b) is
incorrect.
Hence, the
correct option is (B).
