Which of the following systems of distribution offers the best economy
at high voltages?
Direct current system
AC single phase system
AC 3 phase 3 wire system
AC 3 phase 4
wire system
Direct current system
In D.C.
distribution system with comparison to A.C. system, there are following
essential advantages (1) No skin effect.
1. No skin
effect.
2. Corona
power loss is less than A.C.
3. Single
transmission conductors are used i.e. saving of conducting material is more.
Hence, D.C.
distribution is more economy than A.C.
Hence, the
correct option is (A).
