In the right system, it helps reduce reactive power, improves electrical efficiency, and takes pressure off cables, transformers, and switchgear.

being converted into useful work.

That extra current doesn\u2019t always produce useful output; it mainly circulates through the system and creates losses.<\/p><p>A capacitor helps offset that reactive demand. In practical terms, it supplies the reactive power that inductive loads\u2014like motors and compressors\u2014usually pull from the utility.
