The Significance of Reactive Power in Power Systems

What is reactive power?

Which one of the following elements in a power system can generate VARS ?

Reactive power:

Reactive power is a power that is absorbed and then returned to the source by a device in an AC circuit, but it does not deliver energy to the load. Reactive power is expressed in terms of reactive volt-amperes, or vars, and is measured with an instrument known as a power factor meter.

In a power system, reactive power plays a crucial role in maintaining voltage levels and system stability. It is essential for ensuring the efficient transmission of energy.

Reactive power is generated by inductors and is absorbed by capacitors. In this context, the correct option for the element in a power system that can generate VARS is Transformers.

Understanding reactive power is key to optimizing the performance of power systems and ensuring reliable electricity supply to consumers.
