This document provides general guidelines on the preparation of a functional specification for a solid state electronic shunt device used mainly to compensate for voltage fluctuation. The guide covers devices rated to medium voltage (1 kV to 35 kV). In general, these devices contain: a bidirectional converter, an energy storage device, and a coupling transformer connected in parallel. The guide also covers the following equipment to assure proper interface with the electric network including, bul not limited to, voltage and current transformers, disconnect switches, circuit breakers, and three-phase low voltage service for auxiliary power.
