Abstract:Alternating arc single-phase earth faults in 6–10 kV cable networks with insulated neutral are accompanied by over-voltages and a significant increase in the root-mean-square current value at the fault location. When evaluating the specified parameters of transient voltages and currents during arc earth faults, as a rule, the presence of higher harmonics in earth fault current is not taken into account. At the same time, in modern systems of industrial and urban electricity supply, the customers with nonlinear… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
