KVAR is called as Kilo Volt Amps Reactive or 1000Volt Amps Reactive. It is the amount of "imaginary" power in a system. This happens when the voltage and current wave forms are no longer in phase with each other because of inductance\capacitance in an AC system.Current= 1.39 x kVA ( 3 phase 415 Volts) Eg:- 1000 kVA Transformer’s Full load current on LT side 1.443 x 1000= 1443 Amperes ( 3 phase 400 Volts) 1.39 x 1000 = 1390 Amperes ( 3 phase 415 Volts) kW to Current ( power factor assumed as 0.8) Current= 1.8 x kW (3 phase 400 Volts) Current= 1.74 x kW (3 phase 415 Volts) Power in 3 Phase circuit kVAR (Reactive Power) is the vectorial difference between kVA (Apparent Power) and kW (Real Power). kVAR calculation formula: (Reactive Power) 2 = (Apparent Power) 2 - (True Power) 2 which inturn is given as: kVAR(Reactive Power) = √ (Apparent Power) 2 - (True Power) 2 The POWER FACTOR also defines the relationship between kW and kVA. It is the ratio of kW (true power or useful power) to kVA (total power or apparent power). It is a measure of how efficiently electrical power is converted ...

Jun 02, 2018 · Question: Why transformer rating is expressed in kVA instead of kW or kVAR? Answer: At the time of manufacturing, the nature of load to be connected is not known. (i.e it is resistive, reactive, R, RL, RC, RLC or of any other type). Aug 21, 2015 · But, it is clear from the following formula that Power factor is inversely proportional to the kVA i.e. CosФ = kW / kVA Therefore, The Lower the Power factor, the larger the kVA rating of Machines also, the larger the kVA rating of Machines, The larger the Size of Machines and The Larger the size of Machines, The Larger the Cost of machines. The formula for converting kW to kVA is: kW / pf = kVA e.g. 200 kW / 0.8 pf = 250 kVA The formula for converting kVA to kW is: kVA x pf = kW e.g. 250 kVA x 0.8 pf = 200 kW While it can be helpful to have a good idea of the generator size you need, don’t worry if you’re unsure, or you don’t feel confident converting between kW and kVA ...
La conversion d'un kVA en kW est facile à réaliser : pour les particuliers et petits professionnels, on admet que 1 kVA = 1 kW. En revanche, pour les gros professionnels, la conversion est plus compliquée car la puissance réactive entre en jeu.

Dynamic analysis

The var or KVAR rating of a capacitor shows how much reactive power the capacitor will supply. Since this kind of reactive power is caused by inductance, each kilovar of capacitance decreases the net reactive power demand by the same amount. A 15 KVAR capacitor, for example, will cancel out 15 KVA of inductive reactive power. power calculation formula, The transformer calculator uses the following formulas: Single Phase Transformer Full-Load Current (Amps)= kVA × 1000 / V Three Phase Transformer Full-Load Current (Amps) = kVA × 1000 / (1.732 × V)
