How is electrical power measured
Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively. A common misconception is that electric power is bought and sold, but actuall… WebMeasurement of Three Phase Power. Three Phase Electric Power can be calculated to sum of each power value by using separated three power meters. Also, Theory of Brondel said that n-phase electric power can be measured by using n-1 units of power meters. Therefore, three phase power is measured two power meters.
