Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

Reactive power is needed to maintain efficient and reliable operation of the integrated transmission system. However, reactive power cannot be transmitted significant distances, and therefore must be ...

The meters installed on the premises of the micro units to calculate electricity consumption charges do not have provision to calculate reactive power and hence power factor cannot be calculated based ...
