1 General This British Standard gives recommendations for the design of high-voltage open-terminal stations. This standard does not cover equipment included in installations for which separate standards exist. Such equipment should comply with the relevant separate standards. Some relevant British Standards are listed in table 1. 2 International practice Both UK and international practice concerning clearances are included in section 5. International practice is included to allow this standard to be applied to installations designed in the UK for construction overseas. See also note 1 to 1.3. NOTE. The titles of the publications referred to in this standard are listed on the inside back cover. (See also table 1.)
Code of practice for design of high-voltage open-terminal stations
1. Domaine d'application 1.1 Cette norme ne s'applique qu'aux parafoudres à résistance variable en oxyde métallique montés séparément et à ceux qui sont intégrés à un appareil quelconque. Ces dispositifs sont destinés à limiter les pointes de tension dans les circuits à 50 ou 60 Hz en laissant passer le courant de décharge sans couper l'alimentation. 1.2 Les valeurs données en unités SI (métriques) sont la norme. Les valeurs entre parenthèses ne sont données qu'à titre indicatif.

1. Scope 1.1 This Standard applies only to gapless metal oxide surge arresters of separate mounting or those supplied integrally with other equipment. The surge arresters are designed to limit voltage surges in 50 or 60 Hz alternating current power circuits by passing surge discharge current without causing power interruption. 1.2 The values given in SI (metric) units are the standard. The values given in parentheses are for information only.

This standard covers the application of gapped silicon-carbide surge arresters (see ANSI/IEEE Std C62.1-1984 [1]) 1 to safeguard electric power equipment against the hazards of abnormally high voltage surges of various origins. Such overvoltages may cause ?ash-overs and serious damage to equipment, thereby jeopardizing the supply of power to users. It is essential to prevent this by the proper coordination of surge protective devices with the insulation strength of the protected equipment. The subject is a broad one with many rami?cations, and it would require a volume of considerable bulk to explain all possible cases in detail. Section 3 of this standard covers the basic cases for stations used to supply and switch electric power transmission, subtransmission, or distribution feeders. Information is included in Section 4 on application of arresters for protection of overhead distribution systems, both open-wire and spacer cable; underground system cables; all distribution transformers; and other electric distribution equipment. Step-by-step directions toward proper solutions for various applications are provided. For many cases the prescribed steps are adequate. Complex situations or special situations requiring study by experienced engineers are described, but speci?c solutions may not be given. These procedures are based on theoretical studies, test results, and experience.
