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.

Is This Answer Correct ?    25 Yes 26 No
