The character of the voltage at the end of the opened phase conductor was studied and an improved voltage criterion was proposed to distinguish between temporary and permanent single-phase faults. The performance of the improved criterion is hardly i

This paper presents a novel technique for distinguishing between transformer inrush currents and internal fault currents. On the basis of basic morphological transforms and their combined modes, transient current signals can be extracted meanwhile a

This paper addresses a new relaying scheme for identifying the inrush current and short circuit current caused by internal fault on the basis of sudden changes detection using novel morphological gradient (NMG), transient current signals are then ext

A criterion is proposed to distinguish between temporary and permanent faults of shunt compensated EHV/UHV transmission lines. Its compensation criterion is established. In order to improve its sensitivity when resonant frequency is high. The perform

The reflection and refraction of fault-generated wave is discussed. The equations of currents measured by relay in S domain are deduced applying the Peterson principle. The energy ratio of a high frequency component to a low frequency component is ma
