Hey guys
I have been writing up my lab report and I'v run into a sang.
I constructed and analysed a three-phase Y connection similar to the one shown below. Only with resistance values
Red line = 75 + j345.58
White line = 85 + j345.58
Blue line = 95 + j345.58
My theoretical calculated values are (by mesh analysis)
IL(red) = Ip(red) = 0.681<-76.84 A
IL(blue) = Ip(white) = 0.676<44.52 A
IL(whie) = Ip(blue) = 0.664<163.47 A
where Ip = phase current and IL = line current
Vp(red) = 240<0
Vp(white) = 240<-120
Vp(blue) = 240<120
Sp(red) = 37.21 + j159.15 VA
Sp(blue) = 40.68 + j157.06 VA
Sp(white) = 37.12 + j154.9 VA
Now I know how to calculate the Volt Amp reactance and power for each line but I think I need to determine the total power, total volt amps and total volt amp reactance. Can I do this??? how would I go about doing it?
thanks guys
