reactive power is greater in load side compare to generator what will happen?

2 Answers

Answer :

Reactive power is a power that flows back and forth the circuit,it does not perform any work and it is not consumed by the circuit also. In short reactive power can be termed as the unwanted power.
This has to be reduced in order have good power factor .

Description : What is the formula for reactive power?

Answer : The formula for reactive power is, Reactive power = VI sin (phi) The unit of reactive power is VAR ( Volt ampere reactive). The reactive power is denoted by 'Q'. The formula for real power is, Real power = VI cos (phi) The unit of real power is watts. The real power is denoted by 'P'.

Description : How does a capacitor improve power factor?

Answer : Every circuit are usually more inductive than capacitive.it means that the current lags by voltage at small angle.hence we have to compensate this situation so we use Capacitor then this lag is compensate ... angle becomes low and the value of cos(phase angle) is increase and hence power also max.

Description : Explain the term reactive power. Why it is sometimes essential to measure reactive power?

Answer : Reactive power: The reactive power (Q) is defined as the product of voltage(V), current (I) and sine of angle between voltage(V) and current( I) Therefore Reactive power Q = V I ... power so that corrective measures can be taken accordingly to maintain systems power factor near to the unity.
