Can anyone help with a question i have...
An unbalanced star connected load has phase impedances of
Za = 5/30° , Zb = 10/-45° , Zc = 15/60°
The supply is 3phase 4 wire 440v.
Calculate
a) the 3 phase voltages
b) the 2 line currents
im getting confused with the conversion and the 30° lagging
is it?
Delta
Vline = Vphase and both in phase
Iline = √3 x Iphase and lags it by 30°
Star
Vline = √3 x Vphase and leads it 30°
Iline = Iphase and both in phase
thanks in advance...
