Grounding device for electrical networks and electrical installations in the Arctic regions
Abstract The article is devoted to the features of the system grounding and device of electrical networks (EN) and electrical installations (EI) in the continental zone of the Arctic. The traditional grounding devices providing grounding of EN and EI in the Arctic regions are ineffective or their de...
