Why dnt we generate 5-ph or 7-ph supply like as 3-ph supply
Answer Posted / kj
Three phase supply is the least number of phases that will
produce a rotating magnetic filed. This allows 3 phase
induction motors to start without special methods as with
single phase.
Extra phases have been used at times but it increases the
costs of all the power lines.
Where 3 phase can be 3 or 4 wire, 5 phase would be 5 or 6
wire and 7 phase would be 7 or 8 wire.
