49 - Voltage Current and Power in a Balanced 3 - Phase Delta & Star Circuit
In todays video, we are going the consider the relationship between the line and phase voltage, current as well as power in a 3 phase system.
A three phase system is a system or circuit produced by a generator and consisting of three source having the same amplitude and frequency but are out of phase with each other by 120.
Star Configuration
VL = root(3)*Vp
IL = Ip
Delta Configuration
VL = Vp
IL = root(3)*Ip
S = root(3)*VL*IL
P = root(3)*VL*IL cos phi
Q = root(3)*VL*IL sin phi
