An approach to prepare a specification for an electronic device connected in series to compensate voltage fluctuations is presented.This guide intends to provide a base specification to allow users to modify specific parts of the document to meet their practical needs.

This document provides general guidelines for the preparation of a functional specification for solid state electronic devices used mainly for compensation of voltage fluctuation. The guide covers devices rated to medium voltage (1 kV-35 kV). This device contains in general :an inverter, rectifier or dc to dc converter, energy storage device, injection transformer connected in series with the load and normally open by-pass switch. In order to interface these devices with the load additional equipment should be provided including current and potential transformer bypass and isolation breakers and three -phase low voltage service for auxiliary power.

The guide includes technical clauses describing the user's requirements, including operation methods and environmental conditions. It specifies basic requirements of solid state electronic devices used for compensation of voltage fluctuations. Also the guide covers the required installation and start up services.
