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.

∙ 12y agoThe formula you are looking for is kW = amps x volts x 1.73 x pf / 1000.
where kW means 'kilowatts' and pf means 'power factor'.

How do you calculate the phase current when working with a 10kw 3 phase electrical motor?
The 3 phase formula you are looking for is I = HP x 746/1.73 x E x% Eff x pf. Where I = amps, E = voltage, %Eff = percent efficiency of the motor and pf = power factor.
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 you deserve phase 3?
You can get a 3-phase supply in most properties by negotiation with the power company, if your demand for electric power is high enough.
How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate kWh a time component is needed for the hours.
How many amps is 2 hp at 230V 3 phase?
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
How to connect 3 phase power factor correction capacitor?

Calculate watts for a 4160 volt 55 amp 80 power factor 3 phase motor?
317.025280 KILOWATTS = 317,025.28 WATTS
What is the maximum amp for motor 5.5 kw 4 pole 3ph?
power , P=1.732*V*I*power factor so, the formula for calculate the load current for a 3 phase motor is,I=P/(1.732*V*power factor)
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.
How do you calculate power consumption of 3 phase airconditioner unit?
From its nameplate data.
Where would power factor capacitors be installed on a 3 phase motor?
Power factor capacitors can be installed on a three phase motor between the motor contactor and the overload heater block.
How do you calculate the phase current when working with a 10kw 3 phase electrical motor?
The 3 phase formula you are looking for is I = HP x 746/1.73 x E x% Eff x pf. Where I = amps, E = voltage, %Eff = percent efficiency of the motor and pf = power factor.
Why each phase no load power factor of 3 phase induction motor is not same?
That indicates a fault in the induction motor.
What is the formula for calculate 3 phase power MVAR?
Q = 3 Vph Iph sin(phase angle) = 31/2 Vline Iline sin(phase angle)
Why do we use 1.73 as multiplication factor to calculate Phase to Neutral voltage?
because 3Phase power - V X I X Cos Phi X Square root of 3 and square root of 3 - 1.73
