Measurement of three-phase power with the 2-wattmeter

A wattmeter is an instrument with a potential coil and a current coil so arranged that its deflection is proportional to VI cos 6, where V is the voltage (rms value) applied across the potential coil, I is the current (rms value) passing through the current coil, and 6 is the angle between V and I. By inserting such a single-phase wattmeter to measure the average real power in each phase (with
