Abstract

Existing approaches used for HIF detection utilize non-algebraic operations which add to computational complexity, consume more time, use complex algorithms and require a very high-sampling frequency (10-20 kHz). Embodiments disclosed herein provide a method and system for high-impedance fault (HIF) detection in a network. In this method, by shifting a domain digital data one cycle time at a time, and processing associated data, a plurality of Harmonics-based Algebraic Indexes (HAI) that include a half-cycle time domain digital data of a one-cycle time domain digital data, and a magnitude strength of a plurality of non-harmonic frequencies of each of the plurality of digital current signals is determined, which captures information on associated magnitude strength information. Further, a time domain aggregated harmonics-based algebraic index (AHAI) indicating presence or absence of High-Impedance Fault (HIF) in a network being monitored is generated, and accordingly the presence of absence of HIF is detected.
