SVC refurbishment: a cost efficient method to extend the life of an SVC

AbstructIs it possible to refurbish SVCs in a reliable and cost effective way? Installations, which inherently required comprehensive control systems, were first installed in transmission systems in the early 1980’s. Examples include HVDC converter stations and SVCs. At that time the technology used for Control & Protection (C&P) systems was “state of the art”, but the analogue components used then are now obsolete.
