What is the power ratio between power in Star and Delta
circuit?
Answer Posted / priyadharsini
power = 3vicos
in delta Iphase = Iline/rt3.
Vphase = Vline
ie in delta connected ckt P= rt3VphaseIphasecos
IIly in star connected vphase=Vline/rt3,
Iline=Iphase
ie Power = rt3 vpahseIphaseCos
ie. in both star and delta power remain same
therefore the Power ratio = 1.
