Determine the total active power:
Circuit is introduced in the Face 1. It is about a singlewires face for a threephase system. The voltage of the AC source is of 69kV. The source is a balanced source of 60 Hz.The voltage phasor of phase ahasa zero angle:V_{Phase a} = (69/√3) ∠ 0^{o}.
For a given load RL1, we obtain the following three currents for the AC source.The currents are measured so that the direction of the currents is from the bar SRC towards the ground (neutral) but not towards the bar BUS1. The board below indicates values crests
