High speed busbar transfer systems secure a fast and reliable change-over between the main and the back-up power supply sources when the availability of the auxiliary power supply is crucial.
Our compact high speed busbar transfer system (HSBT-Compact) based on the SIPROTEC 6MD85 bay controller allows interruption-free or a short currentless gap transfer between two or three incoming feeders of medium voltage switchgears. This ensures a continuous power supply and safe functioning of auxiliaries in a power plant or an industrial plant.
