700 Amp in 440V System How Much kW?

700 Amp in a 440V three-phase system is approximately 426 kW to 480 kW, depending on the power factor. At 0.8 power factor, the load is about 426 kW, and at 0.9 power factor, it is about 480 kW. First of all the 700 amp means its the current which is flowing in the system and the 440v means its the Voltage or the potential of the running system.

So, if we have to calculate the kW we need power factor so we can take general power factor for putting in the formula to find the answer. As we know that Power is equal to the Product of the Voltage and Current in the system . So now 700 Amp in 440V System How Much kW?

Formula to be used to calculate 700 Amp in 440V System How Much kW?:

Where:

• V = 440v
• I (Amp) = 700 A
• PF (Power Factor) = 0.8 to 0.9 Usually

Calculation:

At Power factor = 0.9 (Which is Very Common)

kW = 1.732 (Value of √3)×440×700×0.9/1000

will be Approx. 426 kW

At Power factor = 0.8

kW = 1.732 (Value of √3)×440×700×08./1000

will be Approx. 480 kW for 700 Amp in 440V System How Much kW?

Overall for Reference:

Power Factor	Power (kW)
0.9	480 kW
0.85	453 kW
0.8	426 kW

Using this formula you can get any load kW of a system if you have the Amps and the ampere can be known by the Ampere meter meter on the system and you can also get the value by the Digital Clamp Meter which will show you the ampere reading. Must use the Power factor for getting the exact kW loading in the system how can get the power factor if not there then you might have to use the another formula.700 Amp in 440V System How Much kW? is generally asked you can also change the value of current as per your calculation

In real life scenario once a engineer have a system for which a digital MFM is used to get the power consumption report so when they take the reading from the meter they get different value and while tallying the value with the main incomer they get stuck so it might have the fault of the CT wiring in the meter may be in wrong polarity hence it is very necessary to do check and with this formulae they found the deviation.

Practical Industrial Example:

A 3 phase motor taking 900 Amps at 440 v then what will be its kW if the power factor is 0.9?

Here,

I = 900 A

V = 440 V

PF = 0.9

Hence applying formula:

kW = 1.732 (Value of √3)×440×900×0.9/1000

will be Approx. 617 kW

Common Mistakes While Calculation

• Must divide the whole value with 10³ i.e 1000 because the value we need is in kW i.e Kilo Watt and kilo = 1000.
• PF should be taken in case of Motor KW calculations.
• Value of ROOT 3 must be accurate to get the accurate valu.
• In many industries 3-phase system have lower voltage 415 too so kindly ensure according to the system for whom you are calculating.
• Proper use of multimeter is advice to get accurate Amps and Volt reading if you are calculating in real world system or live system.

FAQs

1. Why root 3 is there in the formula ?
   – Because we are calculating for the three phase system we are taking root 3 if in case there is single phase system then no need to take this.
   
2. Why there is divided by 1000 in the formula?
   – The value we want is in Kilo Watt hence we need to use 1000 as denominator.
   
3. 700 Amp in 440V System How Much kW? is possible or not.
   – Yes correct question it is.
   
4. if we calculate 700 Amp in 440V System How Much kW? without pf then.
   – the answer you will get may not be accurate.
