要約(英語): High-Speed Earthing Switches (HSES) featuring fast extinction of secondary arcs for EHV/UHV class high-voltage transmission lines were firstly introduced in BPA's 500kV transmission lines in US. The equipment were also applied in Korea's 765kV transmission lines, which technology was developed based on 1990's UHV (Ultra High Voltage) system studies and field test carried out by TEPCO, Japan. For establishing an international standard on HSES, there were several technical issues that need to be addressed. Interrupting duties for the HSES vary depending on the system requirements; such as the system voltage, distance to the adjacent lines, the current flowing in neighboring phases, the parallel line lengths, reclosing scheme, number of circuits on the same tower, the faults conditions and so on. PT48 was established in IEC SC17A in 2009 which was succeeded by WG48 in 2010, and the organization has been working continuously for establishing an international standard on HSES. The aim of this paper is to introduce the technical considerations and prospects for standardization of the HSES as a result of the analyses of the requirement for the HSES system which was conducted by mostly SC17A WG48 Japanese members.
