This applies to industrial lighting, where the lamps are not necessarily incandescent and, therefore, do not represent a resistive load.

In order to calculate the power factor, you need to determine some values by measurement.

To keep the maths simple, we'll have to assume a balanced load.

Using an ammeter and a voltmeter, you can use their results to determine the apparent power. Using an appropriate wattmeter connection, you can determine the true power.

The power factor is then the ratio of the true power to the apparent power.

How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?

To calculate the kWh consumed by a 3-phase motor, you'll need to know both the power factor and operating hours. The formula is: kWh = (√3 x Volts x Amps x Power Factor x Hours) / 1,000. Without the power factor and hours of operation, a precise kWh calculation cannot be provided using just voltage and current.


How do you calculate the phase current when working with a 10kw 3 phase electrical motor?

To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).


How many amps does a 18000 watt generator provide at 120 volt 3 phase service?

The equation for power in a three-phase system is given by the following equation:P = 1.732 x line voltage x line current x power factorSo, to calculate the line current, we can manipulate this equation, as follows:line current = power / (1.732 x line voltage x power factor)As you make no mention of power factor, we shall assume the power factor is 1, and we also need to assume the 230 V you quote is a line voltage, so we can calculate the value of current as follows:line current = 18 000 / (1.732 x 120 x 1) = 86.6 A


Why multiply single phase power by 1.732 to get equivalent three phase power?

Multiplying single-phase power by 1.732 (which is the square root of 3) gives you the equivalent three-phase power because in three-phase systems, the power is not simply additive. The phases are 120 degrees apart, so to accurately calculate total power, you need to account for the phase shift between them. The square root of 3 helps adjust for this phase relationship.


How do you convert 400 amp of three phase supply into kwh?

To convert amps to kilowatt-hours (kWh) for a three-phase system, you need to know the voltage. The formula for three-phase power is: Power (kW) = sqrt(3) x Voltage (V) x Current (A) x Power Factor. Once you have the kW, you can convert to kWh by multiplying by the number of hours the equipment operates.

How do you find whether it is inductor or capacitor if only power factor is given?

in case of inductor or capacitor power factor is always zero.as power factor is cosine of phase angle between voltage and current. in case of inductor and capacitor phase angle between voltage and current is 90 so it become zero so if given power factor is zero then it can be inductor or capacitor.
