because the generator generate apparent power in kilos and it is written as ( kilo volt ampere OR KVA) it is the combination of active and reactive powers where active will be used by the consumers and the reactive will come back to the generator.
If a load takes 50 kW at a power factor of 0.5 lagging calculate the apparent power and reactive power Answer: Apparent power = Active power / Power Factor In this case, Active power = 50 kW and power factor = 0.5 So Apparent power = 50/0.5 = 100 KVA
Active, yes; reactive, no.
The alternating electric current has two components: one active or effective that moves the fan the refrigerator and lights the house and another one that does not do any useful work, but is necessary to sustain the magnetic fields for the induction devices. Both components load the wiring. The non useful component is called reactive component. The active component is measured by the watt-hour meter and the reactive component is measured by var-hour meters. When the load is high, it might be desirable to measure the reactive component to have an idea of the total load called apparent load. The ratio of the active load and the total or apparent load is called the power factor of the supplied load. The power factor varies between 0 and 1.0. The closer to 1.0, the better used the power is. See Reactive Power Management by R. Barreto in Amazon Kindle version.
Reactive power is opposite to Active power. The vector sum of these two powers is apprant power. So reactive power is vector difference between Apprant power & actual power given by Reactive power= Root of (difference between squares of apprant & active power). It is lost power of the system on which power factor depends.
'Active power' (also known as 'true power' and 'real power') is the rate of energy dissipation by the in-phase component of current in an AC circuit, expressed in watts.Active power is the vector-difference between apparent power (measured in volt amperes) and reactive power (measured in reactive volt amperes).Expressed in terms of apparent power: Active Power = Apparent Power x power factor = U I cos (phi)
MVArh represents reactive energy consumption, MWh represents active energy consumption, and MVah represents apparent energy consumption. MVArh is the product of reactive power and time, MWh is the product of active power and time, and MVah is the product of apparent power and time.
Active power is the real power consumed by an electrical device to perform work, measured in watts (W). Apparent power is the combination of active power and reactive power, measured in volt-amperes (VA). Apparent power represents the total power that is supplied to the system, while active power represents the actual power consumed by the system.
Electricity has three terms. Active power - Watt. Apparent power VA, reactive power VAR. Watt is known as active output

'Active' power describes the rate at which energy is delivered to a load and is permanently lost, and is expressed in watts. 'Reactive' power describes the rate at which energy is alternately stored within a magnetic or electric field and returned to the supply every quarter-cycle, and is expressed in reactive volt amperes.You cannot 'convert' one to the other.'Apparent' power is the vectorial sum of active power and reactive power, and is expressed in volt amperes.

The prefix that goes with active is "re-" for the word "reactive," meaning responding to a stimulus or situation.
A watt meter will measure active power, not reactive power.
These terms describe the behaviour of energy in alternating-current circuits.Active power (also known as 'true power' or 'real power') describes the rate at which energy is permanently dissipated by the resistive component of a circuit or load. Active power is measured in watts.Reactive power describes the rate at which energy is alternately stored in the magnetic or electric field and, then, returned to the source when the field collapses, during every quarter-cycle. Reactive power is measured in reactive volt amperes.Apparent power is the vector sum of a circuit's active and reactive power, and is measured in volt amperes.The apparent power of an a.c. load can be determined from the product of a voltmeter and an ammeter reading. The active power can be determined by using a wattmeter. The reactive power can then be determined by vector subtraction.
