[0041] The present invention is further described below in conjunction with the accompanying drawings. The following embodiments are intended only to illustrate more clearly the technical solution of the present invention, and can not limit the scope of protection of the present invention.
[0042] The present invention discloses a process of linkage fault judgment method based on edge computing FTU and fault indicator, such as Figure 1 as shown. It mainly includes the following steps:
[0043] (1) Under normal operating conditions, the Edge Computing FTU and Fault Indicator Shagang have added Beidou / GPS positioning modules to achieve wide-area synchronization based on satellite precision calibration.
[0044] (2) Edge computing FTU sets the ground fault recording start criterion, when the ground fault recording starts, FTU records the absolute time mark of the fault start time.
[0045] Ground fault recording start-up criterion is based on the zero-sequence voltage mutation amou...
