Electrical efficiency is usually expressed as a power factor inbetween 0 & 1, therefore the closer the power factor is to 1, then the more efficiently the kVA is being converted into actual kilowatts. The kW to kVA Formula: Apparent power (kVA) x power factor (pf) = actual power (kW) e.g. 100 kVA x 0.8 = 80 kW; The formula for converting kW

Learn MoreFORMULAS USED IN CALCULATOR: 1-Phase KVA = Volts x Amps / 1000 1-Phase Amps = KVA / Volts x 1000 3-Phase KVA = Volts x Amps x 1.732 / 1000 3-Phase Amps = KVA / Volts / 1.732 x 1000

Learn MoreIn a Generating station, the prime mover (Turbine) generates only and only Active Power.That's why we rated a power plant capacity in MW instead of MVA. Its mean no matter how large your generator is, but it depends on the capacity of the engine (Prime mover/Turbine) I.e. a 50MW turbine connected to a 90MVA alternator in a power plant will generate only 50MW at full load.

Learn MoreAs a result, the KVA power, or the apparent power based on the voltage and current, is higher than the real power. To compensate, the KVA power is multiplied by the power factor, expressed as a decimal between zero and one. Typical power factors for large industrial loads are 0.8, meaning that the KVA power times 0.8 gives the real power in KW.

Learn MoreTransformer insulation is generally rated for 220°C but may be lower for some designs including control or encapsulated. Standards permit the temperature of the transformer enclosure cover to be 65°C over ambient. When temperatures exceed the rating for the insulation system or enclosure, overheating occurs.

Learn MorekVA: apparent power. kVA is a measure of apparent power: it tells you the total amount of power in use in a system.In a 100% efficient system kW = kVA. However electrical systems are never 100% efficient and therefore not all of the systems apparent power is being used for useful work output.
