Kilovolt-Ampere Reactive (kVAR) is a unit that measures reactive power in an electrical system, which is essential for maintaining voltage levels necessary for the safe and efficient operation of electrical equipment. Unlike active power, which performs useful work, reactive power oscillates between the source and load, helping to sustain the magnetic and electric fields that spin motors and flow electricity.
Understanding kVAR is crucial in industries reliant on large motors and transformers, as it helps in optimizing power factor and reducing unnecessary power wastage. Managing kVAR can also lead to significant cost savings by minimizing energy losses and improving overall electrical system efficiency. This unit plays a vital role in ensuring that electrical systems are not only effective but also economically viable.
