Cover Story: Fault analysis is a cornerstone of enhancing resiliency in power grid systems so that electrical distribution companies provide a high-level service. This study aims to provide a compact yet comprehensive review of the state-of-the-art works of fault analysis in transmission power systems. We discuss fault types and several fault-analysis methodologies adopted by relevant research works, propose a novel framework to classify these works, and highlight their strengths and limitations. We anticipate that this survey would be helpful as a literature review and would benefit the research community in choosing suitable techniques for fault analysis. View this paper
