How do you calculate the kW of a 3 phase motor?
For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000.
Is kW same as HP?
Kilowatt to horsepower conversion is one of the most common ones. We’ll convert kW to HP for 3 examples further on: For an average 110 kW gas car (Example 1)…kW to HP Table.
| Kilowatts (kW) | Horsepower (HP) |
|---|---|
| 20 kW to HP: | 26.82 HP |
| 30 kW to HP: | 40.23 HP |
| 40 kW to HP: | 53.64 HP |
| 50 kW to HP: | 67.05 HP |
What is the relation between kW and HP?
A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW). To convert from horsepower to watts, multiply by 746. To convert from watts to horsepower, multiply by 0.00134. To convert from horsepower to kilowatts, multiply by 0.746.
How much power does a 3 HP motor use?
It depends upon load on the motor. If the motor is fully loaded, it will provide output power of 3HP = (3 X 0.746) kW = 2.24 kW. Electrical input power = output power / (Efficiency /100). Unit consumed = Power in kW X numbers of hours of operation.
How do you calculate kW from HP motor?
Electric Horsepower to Kilowatts Since one electric horsepower is equal to 0.746 kilowatts, the formula to find kilowatts is to multiply electric horsepower by 0.746.
What is one watt power write the relation between horsepower and Watt?
Horsepower is related to watt as: 1 horsepower = 746 W = 750 W approximately. 1 horsepower (HP) = 750 watt (approx.) The power is one watt when one joule of work is done in one second.
Is kWh the same as kW?
A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. The difference between kWh and kW, and what you see on your bill, is that kW reflects the rate of electricity you use, and kWh indicates the amount of electricity you use.
What is the formula for kW?
We find the power in kilowatts P(kW) by dividing the power in watts P(W) by 1,000. Here’s the Formula for Converting Watts Into Kilowatts: P(kW) = P(W) / 1,000.
How do you convert kW to hp?
Kilowatts to metric horsepower. One metric horsepower is equal to 0.73549875 kilowatts: 1 hp(M) = 735.49875 W = 0.73549875 kW. So the power conversion of kilowatts to horsepower is given by: P(hp) = P(kW) / 0.73549875.
How do you convert kW to horsepower?
A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW). To convert from horsepower to watts, multiply by 746. To convert from watts to horsepower, multiply by 0.00134.
What is the formula for 3 phase electric motor?
Perform a three-phase power calculation using the formula: P = √3 × pf × I × V Where pf is the power factor, I is the current, V is the voltage and P is the power.
What is the formula for calculating kW?
In order to calculate kw units we have formula as kw=VIcos(theta) where v is the voltage ,I current,theta angle between v and I . If we want to calculate KVA rating then use formula KVA=kw/cos(theta).
