Good Day,

I am hoping that someone is kind enough to teach me how find the True Power in Watts when Reactive Power in VAR is given in a 3 Phase power 440 Volts system. I need to know the formula. Thanks in advance!

 

You don't know. It's like asking for a formula for how many gallons of gas you need if your car gets 25 miles to the gallon. The two are related, but you lack a piece of information to tie it all together.

In this case, you need either the power factor or the apparent power.

 

Sorry for the lack of data to my query. Here are the other info: 2,040 KVA, 87% pf and 440 volts 3 phase system. Thank you for your attention!

 

So you don't need the VARs. Real power (W) is the apparent power (VA) times the power factor.
