Abstract: A system for a wind turbine that includes a protection system interfaced to a circuit breaker system and a sensing system. The protection system is configured to determine an operational mode of the wind turbine by monitoring at least two parameters determine a parameter set comprising a plurality of operational parameters based on a determined operational mode, and an associated set of expected values corresponding to the parameter set, determine actual values corresponding to the determined parameter set, identify a fault condition in the event that the determined set of actual values of the operational parameters do not correspond to the determined set of expected values of the operational parameters, and implement a protection action based on the identified fault condition.

Abstract: A cabinet For electronic components, the cabinet comprising an outer wall, a closure, and an attachment structure, the cuter wall encapsulating an internal space and forming an opening, the closure being attached to the outer wall by the attachment structure, and the attachment structure allowing movement of the closure relative to the outer wall between an open position where the opening is uncovered and a closed position where the opening is covered by the closure. To enable automatic and fast opening of the cabinet in case of over pressure, e.g. caused by arching of electronic components in the cabinet, the cabinet Further comprises a magnet structure comprising at least one magnet arranged to hold the closure in the closed position and to release the closure in response to a pressure in the internal space.
