The equations to find real power is:
P = 3 x Vphase x Iphase x cos(v - i)
or √3 x Vline x Iline x cos(v - i)
My question is if you have a delta connected 3 phase system and have
Vphase = Vline = 120 angle 0
Iphase = 41.6 angle -36.87
Iline = 72.05 angle -66.87
Would you use the angle of 36.87 for both the real power equations?
