Answer» The TWO Wattmeter Method is explained, taking an example of a BALANCED load. In this, we have to prove that the power measured by the Two Wattmeter i.e. the sum of the two wattmeter readings is equal to root 3 TIMES of the phase voltage and line voltage (√3VLIL Cosϕ) which is the actual power CONSUMED in a 3 phase balanced load. |
