How many KVA makes 3300 watts?

We can easily calculate it by using our Power Triangle Formula. It is the most authentic method of calculating the Watts from KVA or vice versa.

Where;

S = Apparent Power = KVA
P = Actual Power or Real Power = KW
Q = Reactive Power = KVAR

If we have Power factor known, then it is very easy to determine the other values. If p.f is not known, we assume the power factor to be 0.8 or 0.9 for an equipment or a system.

Let’s say we have a generator of 10 KVA, with a p.f of 0.8 lagging, then we can easily calculate the KW in this way.

p.f = KW/KVA

Just plug in the values.

0.8 = KW/10

KW = 10*0.8

KW =8

SO WE GET A POWER OF 8000 WATTS


In your case, lets assume,we have p.f of 0.8 and 3300 watts, so calculate KVA’s in this way;

p.f = KW/KVA

0.8 = 3.3/KVA

OR

KVA = 3.3/0.8

KVA = 4.125

Or;

4.125 kVA MAKES 3300 WATTS.
