WebNov 30, 2024 · Therefore, electrical usage is a measurement of watts used over a period of time. Your electric meter records electricity usage in kilowatt-hours. In simple terms, 1 kilowatt hour = 1,000 watt-hours. For example, if you turn on a 100-watt light bulb for 10 hours, the energy usage is calculated as 100 watts x 10 = 1,000 watts (or 1 kilowatt hour). WebNov 12, 2024 · Perform a three-phase power calculation using the formula: P = √3 × pf × I × V . Where pf is the power factor, I is the current, V is the voltage and P is the power. Single-Phase vs. Three-Phase Power. …
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.
