A High Speed Transfer System which comprises three Protection and Control devices. A first and a second of said Protection and Control devices are used for failure detection on the feeder bus-bar; the third of said Protection and Control devices is used for the High Speed Transfer System co-ordination functionalities.

High speed transfer system

System and methods for coordinating the control system of a switched power capacitor with an integrated resonance protection function. The coordination system coordinates the function of a switched power capacitor's primary control system and resonance protection system to avoid duplication of tasks and on/off operation deadlock. The coordination system adjusting calculations made by the primary control system in response to a determination of a harmonic resonance condition by the resonance protection system.
