Negative kVAR (reactive power) indicates that power is being fed back into the grid, which often happens when a generator, such as a synchronous condenser or battery storage system, supplies reactive power. This can be beneficial for voltage support in the grid, improving stability and efficiency. However, excessive negative kVAR can lead to overvoltage conditions, which may cause equipment damage or operational issues. Managing reactive power effectively is crucial for maintaining power quality and grid reliability.

kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
{| |- | 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). |}
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.

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 = kva*sin@
KVAR - FM - was created in 2008.
Kvar stands for killo volt amp reactance.
It makes a positive.
