I'm not sure the question makes sense. In a word, "yes". Think of a simple DC source and a resistor. No reactive power there, but power is being dissipated by the resistor ("transferred" from the DC source).
If you're talking about AC circuits and "transferring" means going through a transformer, then, again, "yes" because whatever reactance the transformer has can be offset by a capacitor with the same. So you would have no reactive power, but power would be transferred.

What is reactive power and its significance?
'Reactive power' is the rate at which energy is stored in an electric or magnetic field, and returned to the supply. To differentiate between reactive power and true power (the rate of heat transfer and of work), and for no other reason, it is expressed in reactive volt amperes (var) rather than in watts (W). Its significance is that it is necessary to establish and sustain electric and magnetic fields.
What is the unit of measure for reactive power?
Volt Amps [volts times amps] is used for reactive and apparent power. Watts (dimensionally the same as volt amps) is used to indicate real power.AnswerReactive power is measured in reactive volt amperes (var).
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 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.
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.
Why wattmeter measure the reactive power?
A watt meter will measure active power, not 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.
Which excitation synchronous motor drawn reactive power?
Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.
What is the use of reactive power in electric circuitry?
'Reactive Power', which is expressed in reactive volt amperes, describes the rate at which energy is alternately stored (in a circuit's electric or magnetic field) and returned to the a.c. supply when the field collapses. It differs from true power, expressed in watts, because true power describes the rate at which energy is permanently lost by heat transfer due to the resistive component of the circuit.Reactive power doesn't 'have an use', per se, it's merely a way of quantifying the movement of energy in the reactive component of an a.c. circuit.The vector sum of a circuit's reactive power and its true power is called the apparent power of the circuit, expressed in volt amperes.
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'.
What is different between active power and reactive power?
'Active power' describes the rate at which energy is dissipated by a circuit through heat transfer, or (e.g. in the case of a motor) provides useful work. 'Reactive power' describes the rate at which energy is alternately stored within an electric or magnetic field and, then, returned to the supply every quarter-cycle.
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.
