Wiki User
∙ 10y agoThe unit used to measure reactive power in an AC electric power system is the volt-ampere reactve (var). Reactive power exists in an AC circuit when the current and voltage are not in phase.

What is a VA in electric circuit?
VA or, more correctly, V.A, is the symbol for volt amperes, which is the unit of measurement for the apparent power of an alternating-current load.In A.C. circuits, true power (measured in watts) is a measure of the rate at which energy is supplied to the load, and reactive power (measured in reactive volt amperes) is a measure of the rate at which energy is alternately stored in the circuit's magnetic field and returned to the supply. Apparent power is the name given to the vector sum of true power and reactive power.
What instrument can you use to measure reactive power of a load?
An ammeter and a wattmeter are the instruments needed.
Why reactive power is named as reactive?
Actually reactive power is a power which flows in between load to source which is a reactive action of the power given from source to load.the given power to load will not be utilised fully.some power will be oscillating from load to source.this is called reactive power.
What is the electrical term VAR?
Seeing as how this question is under Home Electricity the term VAR stands for Volt Amps Reactance.See related links belowVAR is a term for computer distribution business. Which stands for Value Added Retailer.
What happens to reactive power in a circuit that has both inductance and capacitance?
Inductors are considered to be a load for reactive power, meaning that they will draw reactive power from the system. Capacitors are considered to be sourced of reactive power, they feed reactive power into the system. If you have a circuit that is at unity (balanced with inductors and capacitors) no reactive power will be drawn from the source. You will have unity power factor. If your circuit is more inductive than capacitive it will be drawing reactive power from the source. The opposite is also true for capacitors.
Why wattmeter measure the reactive power?
A watt meter will measure active power, not reactive power.
Unit of reactive power?
Reactive power is measured in reactive volt amperes (var). Note that this is a 'traditional unit', as SI doesn't recognise anything other than the watt -regardless of the 'type' of power!
Is the kilowatt apparent power?
According to Wikipedia, all forms of power can be expressed in Watts, but typically one expresses only REAL Power in Watts (& Kilowatts).The standard is to express Apparent Power in Volt-Amperes (VA) (& KVA).The kilowatt is the unit of measure for true power; apparent power is measured in volt amperes.However, the volt ampere and the reactive volt ampere (for reactive power) are traditional units, used to help differentiate between apparent, true, and reactive power. SI recognises the watt as the unit for each.

The unit used to measure electrical power is the?
The Watt is the unit used to measure electric power :)
Can reactive power measure by 2 wattmeter method?
Active volts amperes are measured by 2 wattmeter methods. A wattmeter will measure active power and not reactive power. Electrical engineering is a promising career for anyone who likes to generate power.
Why VAR meter does not measure real and apparent power?
A VAr meter only measures the reactive (imaginary) power. Apparent power is a combination of real and reactive power; thus having a VAr meter will not suffice to measure apparent power. Likewise, because the VAr meter only measures reactive power, it does not provide any information on real power.
By what name is power expressed in?
the unit of power is defined as the WATT unit of measure , as a standard international unit
What instrument can you use to measure reactive power of a load?
An ammeter and a wattmeter are the instruments needed.
What is reactive volt amps?
volt ampere reactive is the unit of reactive power.It is the power which does no useful work but is required to assist in performing work,such as setting up magnetic fields in motors and transformers.It is also called as imaginary power.It occurs in purely reactive circuit i.e. purely inductive or capacitive.The inductance absorbs the reactive power and capacitance injects the reactive power.In inductance,reactive power is utilised to develop the flux while in the capacitance,the reactive power's function is to store the charge.
What is unit dB mean?
databand-a unit to measure gain power
What does KVR mean in electrical?
I think you probably mean 'kvar' (lower case), and stands for 'reactive kilovolt amperes'. This is the traditional unit used to measure the reactive power of an a.c. load. Reactive volt amperes are used to measure the rate at which energy is continually supplied, stored in the circuit's magnetic or electric field and, then, returned to the supply, every quarter-cycle. Some books refer to it as 'wattless power' or 'imaginary power' -although, in this sense, 'imaginary' is a mathematical term for 'quadtrature' or being 'at right angles' to true power measured in watts.
