{| |- | capacitance of the capacitor is mentioned in KVAR. Formula : KVAR = KW*tan@ FOR tan@, First note the power factor & KW without connecting capacitor. The noted power factor is in cos@.Convert the cos@ value in tan@. for ex. If power factor is 0.6, KW = 200 cos@ = 0.6 cos-1 (0.6) = 53.1 tan (53.1) = 1.333 200*1.333 = 266.6 KVAR if you use 266 KVAR capacitor, Then the power factor improves to unity (1.000). |}
Kilowatts (kW) measure real power, which is the actual power consumed by electrical devices to perform work. Kilovars (kVAR), on the other hand, measure reactive power, which is used to maintain the electric and magnetic fields in inductive and capacitive components. The relationship between kW and kVAR is important in understanding power factor, as they combine to define the apparent power (measured in kVA) in an AC circuit, through the equation: ( \text{kVA}^2 = \text{kW}^2 + \text{kVAR}^2 ). A higher kVAR can indicate inefficiencies in a system, requiring correction to optimize power usage.
KVAR, or kilovolt-ampere reactive, is used to measure reactive power in an electrical system. It is essential in AC power systems to quantify the power that does not perform any real work but is necessary for maintaining voltage levels and supporting the magnetic fields required by inductive loads like motors and transformers. KVAR is crucial for maintaining power factor and ensuring efficient operation of electrical systems.
It depends upon at how much voltage level 400 kvar capacitor bank is used.

kvar
Kvar = Kilo Volt Amp Reactance.
The KVAR will be 1249.75, the power factor is .7. KVAR = sqrt [ KVA^2 - kW^2 ]
kvar = kva*sin@
KVAR - FM - was created in 2008.
kvar = kva*sin@
Kvar stands for killo volt amp reactance.
420 micro farad=1 kvar
A negative KVAR reading can be eliminated by adding an inductor to the circuit.
kvar (pronounced phonetically [kah-Vahr])
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
