Among the
following statements which one is true?
a.c. transmission is more efficient
d.c.
transmission is more efficient
both are equally efficient
low voltage d.c. transmission is more efficient
d.c.
transmission is more efficient
High voltage
direct current (HVDC) transmission is more efficient when we have to transmit
power over long distances, although cost is a factor in HVDC system but it
provides great stability, reliability and transmission capacity. Researches
have shown if the transmission line route is longer than about 300 miles, DC is
a better option because AC lines have more line losses than DC for bulk power
transmission.
Hence,
the correct option is (B).
