Enter the apparent power in kVA (kilovolt amp), power factor between 0 to 1, then press the calculate button to get the reactive power in kVAR (kilo Volt-Ampere reactive). Enter Apparant Power (kVA): kVA
kVAR to kVA Calculator: Enter the reactive power in kilo volt-ampere reactive, power factor between 0 to 1.
4 Ιαν 2022 · Calculate the kVA using the net kW and net kVAR (i.e. kW imp - kW exp as well as kVAR imp - kVAR exp) since this is the capacity of the power flow that the utility must be able to handle.
The required kVAR capacity can then be calculated as C = (150 kW) x 0.58 = 87 kVAR. If kW or present power factor is not known you can calculate the required compensation using the following formulas (appli-cable for 3 phase supply only) to get the 3 basic pieces of infor - mation required for calculating kVAR: P.F. = kW (Real Power) kVA ...
KVAR is Reactive Power. It is the power that magnetic equipment (transformer, motor and relay) needs to produce the magnetizing flux. KVA is Apparent Power. It is the “vectorial summation” of KVAR and KW.
The kW kVA kVAR formula: kVA is equal to square root of the sum of square of the kW and KVAR. kVA2 = kW2 + kVAR2, kVA = √ (kW2 + kVAR2), kVAR = √ (kVA2 - kW2)
KVA (Kilovolt-Ampere) measures apparent power, which is the vector sum of reactive (KVAR) and active power (KW). While KW contributes to work, KVAR is essential for maintaining voltage levels that enable KW to perform work efficiently.
