| 摘要 |
The present invention is related to a device and a method for detecting faults in an electrical system (104, 1004). The fault detection device (108, 207, 300) comprises, a first measuring unit (301) configured to receive a first error value indicative of a fault in a subset (218) of a plurality of components (208), a communication unit (310) configured to provide information to a user interface (312), a second measuring unit (302) configured to be electrically connected directly to each of at least two of the plurality of components (208), and a processing unit (304) connected to and configured to control the first measuring unit (301), the second measuring unit (302), and the communication unit (310). The second measuring unit (302)is configured to, based on the first error value,determine a operational status of each of the components in the subset (218). |
