A three-phase source has a phase sequence of EAS- Esc - ECA and delivers the following delta load currents: Ib 1220° A, I = 12Z - 60° A. I. = 16260° A. The line voltage EAB is 230Z0° V. If one wattmeter is connected with its current coil in line A and its potential coil across lines A and B, and a second wattmeter is connected with its current coil in line C and its potential coil across lines C and B, what will each wattmeter register, and what is the total power?
