摘要： A processing module (50) for use in conjunction with at least one capacitor (30) included in a converter (100) for conversion of alternating current power to direct current power, or vice versa, is disclosed. The processing module (50) is configured to receive values of sensed current (I cap ) flowing into the at least one capacitor (30) and possibly values of sensed voltage (I cap ) over the at least one capacitor (30). According to embodiments of the present invention, sensed current (I cap ) flowing into the at least one capacitor (30) and possibly voltage (I cap ) over the at least one capacitor (30) may be utilized in order to provide or generate an indication of any possible failure or onset of failure of the at least one capacitor (30). A method (300) in the processing module (50) and system (200) comprising the processing module (50) are also disclosed.
摘要翻译：公开了一种用于与包括在转换器（100）中的至少一个电容器（30）结合使用以将交流电力转换为直流电力或反之亦然的处理模块（50）。处理模块（50）被配置为接收流入至少一个电容器（30）的感测电流（I cap）的值以及可能的感测电压值（I cap >）在至少一个电容器（30）上。根据本发明的实施例，在所述至少一个电容器（30）上流过所述至少一个电容器（30）的感测电流（I cap）和可能的电压（I cap）可以使用电容器（30）以便提供或生成至少一个电容器（30）的任何可能的故障或故障开始的指示。还公开了包括处理模块（50）的处理模块（50）和系统（200）中的方法（300）。

摘要： The invention concerns a current limiting device (41) for a high voltage equipment (20) in a high voltage direct current power system, where the equipment comprises a disconnector operable to obtain a mechanical separation from a power line conductor (44) of the system. The invention also concerns a high voltage direct current arrangement and a high voltage power system comprising such a current limiting device (41). The current limiting device (41) comprises a first current limiting circuit (42) for connection between the power line conductor (44) and a first connection terminal (Ti) of the equipment (20) and the first current limiting circuit (42) is operable to reduce alternating currents in the frequency range of 70-200 kHz.
