Every electric loads that works with magnetic fields(i.e: motor,chokes,Transformers,inductive heating,arc-welding generators etc)produces a varying electric lags which is called INDUCTANCE.The lag of inductive loads maintain the current sense(eg: Positive) for some time and the negative going voltage tries to reverse it.These phase shift between current and voltages have to be maintained.The current and voltage have opposite sign.During this time the negative power or energy is fed to the network/circuit.When current and voltages have same sign again,the same amount of energy is required to built up the magnetic field in inductive loads.This magnetic reversal energy is called Reactive power.In AC circuit (50 Hz - 60 Hz) this process repeated 50 to 60 times a second.So an obvious solution is to briefly store the magnetic reversal energy in capacitor and relieve the network (the supply line)of this reactive energy.

Which line requires compensation?
Basically an AC transmission line require compensation in terms of reactive power. To push the active power across a transmission line certain amount of reactive power is necessary. In AC transmission line reactive power is generated and consumed. Generator is responsible for the production of reactive and active power both. Than this reactive power is consumed by the load and transmission line. Additional reactive power s supplied by the capacitor. This extra power supplied by the capacitor is termed as reactive power compensation. Requirement of this reactive power is there because reactive power is necessary to maintain the voltage stability.
What is the name for freshly generated hyrogen in a reactive form?
The term for freshly generated hydrogen in a reactive form is nascent hydrogen.
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 term for freshly generated atomic number 1 in reactive form?
The term for freshly generated atomic number 1 (hydrogen) in a reactive form is nascent hydrogen.
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.
Which excitation synchronous motor drawn reactive power?
Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.
How can you reduce reactive power?
If, for example, the reactive power of a load is due to its inductance, then installing a capacitor in parallel with the load will reduce the overall reactive power.
Is that the reactive power is a combination of both reactive power and imaginary power?
No. It is apparent power (expressed in volt amperes) that is the combination (vector sum) of true power (expressed in watts) and reactive power (expressed in reactive volt amperes). 'Imaginary power' is simply another name for 'reactive power' -where 'imaginary' is simply mathematicians-speak for 'quadrature' or 'right angles'.
Is reactive power a vector or scalar?
I am not sure what exactly you mean by "reactive power" (I guess you mean electrical reactive power), but power is the ratio of energy for a period of time. So that makes power (and reactive power as well) a scalar, since you can describe it with only one number. The fact that electrical reactive power is drawn on a XY plane, should not confuse you.
Is reactive power greater than true power?
Use a wattmeter, as it only reads 'real power' of your load. Use an ammeter and a voltmeter, and the product of the two readings will give you 'apparent power' of your load. Since apparent power is the vector sum of real power and reactive power, use the following equation to find the reactive power of your load: (reactive power)2 = (apparent power)2 - (real power)2
How much of the uk's power is generated by nuclear power?
20% of the worlds power is generated by nuclear power
