High‐impedance fault (HIF) and load variation signals are sampled using EMTP‐RV and exported to MATLAB. DWT is applied to extract features, which are then input into the SVM algorithm to detect HIFs and distinguish them from other network phenomena. ABSTRACT High impedance faults (HIFs) can lead to crucial damage to the utility grid, such as the risk ...

This paper proposes a feature fusion method for oscillating wave signals based on multidimensional transformation. For warpage and interturn faults in transformer windings, the fault information is extracted using the oscillating wave method. By fusing optimal multifeatures from different dimensions in the time–frequency domain, this approach enables ...

The Influence of Atmospheric Overvoltages on High-Voltage SF6 Substations [PDF]
Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented ...
