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.
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.
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)).
To calculate the amperage of a 1250 HP motor at 4160 volts in a three-phase system, you can use the formula: Amperage (I) = (Horsepower × 746) / (Voltage × √3 × Power Factor). Assuming a power factor of around 0.9, the calculation would yield approximately 174.5 amps. Therefore, a 1250 HP motor at 4160 volts would draw around 174.5 amps in a three-phase system.
To calculate LRA (Locked Rotor Amperes) to tonnage in a three-phase system, first determine the LRA value of the motor, usually provided on the motor nameplate. Then, use the formula: Tonnage = (LRA × Voltage × √3) / (3,517 × Efficiency × Power Factor), where the voltage is the line-to-line voltage in volts, and the efficiency and power factor are the motor's operational values. This will estimate the cooling capacity in tons based on the motor's electrical characteristics.
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
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.

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.
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)
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.
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)).
Power factor capacitors can be installed on a three phase motor between the motor contactor and the overload heater block.
For a 1.5 hp 230v 3 phase motor, you can calculate the amperage using the formula: Amps = (HP x 746) / (Volts x Efficiency x Power Factor x √3). Assuming an efficiency of 0.85 and a power factor of 0.8, the amperage draw would be approximately 4.3 Amps.
From its nameplate data.
That indicates a fault in the induction motor.
