HVDC Disconnectors
$0.00
Description
Disconnectors (DSC) for HVDC applications are designed to specific constraints and requirements typical for DC applications, that are quite different compared to AC applications. They are requested to withstand DC voltage open gap and to ground to ensure safety for the people in the substation and to permit proper and safe layout configuration. In some cases, like for filter applications, they are requested to break a sum of harmonic currents at a certain voltage (amply smaller than the rated voltage of the disconnector) due to the ripple created by harmonics on the reactances.
