WebPerforming a 3-phase power calculation means using a simple formula relating the power to the voltage, current and a power factor describing the efficiency of the circuit. The key difference between working out power for 3-phase and single-phase systems is a factor of the square root of three. WebMay 17, 2024 · The error in your calculations stems from not considering 2 equal currents from each line, with a phase difference between them, when the 208V lamps are connected line to line. Those currents would be (1200 x 20)/208=115.4A. The resultant of those currents would be (115.4*√3)=200A. Share Cite Follow edited Jun 7, 2024 at 11:32 WebThe two-wattmeter method is the most commonly used method for three-phase power measurement. The two wattmeters must be properly connected to any two phases, as shown typically in Figure.(2). ... If the line voltage is 220 V, calculate: (a) the per-phase average power, (b) the per phase reactive power, (c) the power factor, and (d) the … nett\u0027s kitchen catering
