    Abstract: A protection arrangement for an uninterruptible power supply system including at least one vacuum circuit breaker connected in series with an inductive element, the protection arrangement including a first bypass branch and a first grounding branch, the first bypass branch being connected in parallel with the inductive element and including two series-connected protective components of a first type and a bypass branch midpoint between them, where the first grounding branch is connected between the bypass branch midpoint and ground and includes a first grounding surge arrester.

    Abstract: A protection arrangement for a multiphase uninterruptible power supply system including a vacuum circuit breaker connected in series with an inductive element, where the inductive element includes, for every phase, two series-connected magnetically coupled windings separated by a tap point. The protection arrangement includes one first group of protective components per phase, each first group including a first protective component having a first end connected to a link between the vacuum circuit breaker and the inductive element and a second end connected to a corresponding tap point, where at least one protective component in each first group is a surge arrester.
