When a high impedance fault (HIF) occurs in a distribution network. the detection efficiency of traditional protection devices is strongly limited by the weak fault information. In this study. a method based on S-transform (ST) and average singular entropy (ASE) is proposed to identify HIFs. https://countryscenesaddleryandpetsuppliers.shop/product-category/halter-bridle-bag-with-3-hook-rack/
