How Do You Convert Three-Phase Power To Amps?
Three-phase electric motors are used in industry and home emergency generators. All three outputs carry the same current, and power transfer remains constant, flowing into a linear and balanced load. To make a conversion power to amperes (amps), you need to know the voltage and power factors of the electric motor. Power factor defines a delay between the voltage and the actual electrical current flow. The identification nameplate of most large electrical motors that use three-phase power contains this number. Be sure that your measurements are in the standard units. For a motor or generator in kilowatts, convert it to watts: 1 kW = 1000 Watts. Obtain the voltage measurement if not already provided. Use a quality digital voltmeter to measure the voltage line-to-line between any two of the three outputs. Find the power factor (p.f.) on the identification nameplate. For a purely resistive circuit, the power factor equals 1.0 (perfect). Use the Ohm’s law formula: Power (watts) = Voltage (v
