Shunt reactor technology: Three world records in three years

Abstract
Variable shunt reactors (VSR) with on-line tap changers are a cost-effective solution for compensation of reactive power and maintaining voltage stability, especially with the growing use of renewable power sources characterized by volatile demand of reactive power. Shunt reactor technology is based on an iron core design with air gaps which must be created to ensure mechanical stability with low vibration and noise. The wide regulation range of a VSR provides the correct amount of reactive power in small enough steps to avoid it switching on and off, thus preventing big switching impulses in the grid. For off-shore wind parks, the ester-filled shunt reactor is a promising solution which increases environmental safety
