Shunt compensation is often used to stabilise voltage on power systems. The switched devices are used for relatively slow speed applications but the faster forms are capable of following very rapid load changes such as a steel rolling mill or even an arc furnace. The load variations of an ac traction system may sometimes be large enough to disturb the supply system but these problems have until now been solved without compensators. However shunt compensation has been used for phase balancing purposes. On ac railway systems there is also considerable advantage to be gained from control of the catenary voltage by means of single phase compensators since the maximum distance between substations is often governed by voltage regulation.
