Abstract: An arrangement for cooling a high voltage converter including a major loop with a pump for making a coolant liquid to pass power semiconductor devices of the converter and a heat exchanger for lowering the temperature of the coolant liquid before passing the power semiconductor devices again. An extra loop is connected to the major loop. The extra loop has a cooling apparatus containing a volume of a cooling medium and adapted to cool the medium to a temperature substantially lower than the temperature of the coolant liquid after having passed the heat exchanger in the major loop. A control unit is adapted to divert at least a part of the coolant liquid to flow through the extra loop when the need of cooling the power semiconductor devices of the converter is extremely high.

Abstract: A Compact Secondary Substation including a fault protection system and a method for fault protection in Compact Secondary Substations (CSS). The CSS includes a Ring Main Unit (RMU), a transformer and a Low Voltage (LV) switchgear. The CSS includes a number of detectors, which detectors can be placed at least in one of the RMU, the transformer or in the LV switchgear, which detectors can be connected to a control unit, which control unit by fault detection by the detectors can activate a fast operating switch for grounding. By using the fast operating grounding switch and controlling this on the basis of the detectors placed inside the CSS, an active arc fault protection is achieved. The control unit also controls the fast operating grounding switch so that it works as a working grounding switch.
