How to Calculate KVAR Rating
How to Calculate KVAR Rating in Electrical Panel :
First we must know these three values:
Load = ?
Power Factor = ?
Achive = ?
Example-
Load = 150 kW
PF = 0.70
Achive = 0.99
Answer:
Formula- KVAR = P (tanØ1 - tanØ2)
Here,
1. CosØ1=0.7
Ø1=Cos-1(0.7)
Ø1=45.57
2. CosØ2=0.99
Ø2=Cos-1(0.99)
Ø2=0.10
put the value in formula-
KVAR = 150{tan(45.57)-tan(0.10)}
KVAR = 150(1.02-.14)
KVAR = 150(.88)
KVAR = 132
