A negative KVAR reading can be eliminated by adding an inductor to the circuit.
It is a rating that is used to size capacitors in microfarad. MFD is an acronym for the word microfarad.
kvar = kva*sin@
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
To calculate the reactive power (kVAR) for a 30 hp motor, first convert horsepower to kilowatts using the formula: 1 hp ≈ 0.746 kW, so 30 hp is approximately 22.36 kW. Then, determine the power factor (PF) of the motor, typically around 0.8 for industrial motors. You can calculate the kVAR using the formula: kVAR = kW × √(1 - PF²). For a 30 hp motor with a power factor of 0.8, the kVAR would be approximately 13.8 kVAR.
To convert kilovolt-amperes reactive (kVAR) to microfarads (μF) for capacitors, you can use the formula: ( C = \frac{1000 \times kVAR}{2 \pi f V^2} ), where ( f ) is the frequency in hertz and ( V ) is the voltage in volts. As a general approximation at 60 Hz and a voltage of 240V, 1 kVAR is roughly equivalent to around 41.67 μF. The exact value will vary based on frequency and voltage levels used in the specific application.

{| |- | 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). |}

The formula is that kW^2 + kVAR^2 equals kVA^2 or if you prefer, the kW and the kVAR are the two sides of a right angled triangle and the kVA is the hypotenuse. So here you have a 3-4-5 triangle times 140, in other words 420-560-700, and the kVAR is 420.
Kvar = Kilo Volt Amp Reactance.
The KVAR will be 1249.75, the power factor is .7. KVAR = sqrt [ KVA^2 - kW^2 ]
KVAR - FM - was created in 2008.
