How many capacitors should I use for 300KVAR

There are two types of power in any electrical distribution system: real power (KVA) and wasted power (KVAR). Real power is the power that your electrical distribution system uses to deliver what you want from your device without any waste of energy. Electrical heaters, fluorescent bulbs, and similar devices use real power.. . A system’s entire amount of power in use is indicated by the unit kVA, which measures perceived power. kW Equals kVA in an entirely efficient system. Electrical systems are never 100% efficient. Thus, not all of. . A power factor between 0 and 1 represents electrical efficiency; the closer the power factor is to 1, the more effectively the kVA is transformed into usable kW. The power factor of generators is 0.8. Active power (kW). . Reactive power is known as KVAR (Kilo Volt Ampere Reactive or Reactance). It is the force needed to magnetize flux that magnetic devices like transformers, motors, and relays create. Understanding kW and kVA is necessary. [pdf]
