## Abstract

A Reactive regulator capable of introducing reactive powers in an AC electrical system in order to satisfy the reactive power demanded by the loads of such electrical system in a gradual way, when demanded, and in as many stages as necessary to improve the efficiency and viability of such electrical system by having ways to vary the voltage on one or more reactive elements through a coupling element, transformer, autotransformer or any other type of variable voltage drive, whose primary is connected to an electrical system through terminals and the secondary is connected to a reactive element through at least one switch, of solid state or not, which allows the connection of a mobile terminal to any of the derivations of the secondary of the coupling device.
