1 Domaine d’application 1.1 Inclusions Cette norme s’applique à la conception, à l’installation, au fonctionnement, à l’entretien et aux essais des groupes électrogènes et l’équipement connexe dont le rôle est d’assurer l’alimentation électrique de secours des charges électriques : a) dans des bâtiments ou des installations en cas de panne de l’alimentation normale, lorsqu’une alimentation…

1.1 Scope [ Replace this clause with the following] This Standard applies to cast aluminium alloy enclosures pressurized with dry gases and gas mixtures (see Note 1) used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric or arc-quenching properties, with rated voltages – of 1 kV and up to and including 52 kV,…

1 Scope This document applies to wrought aluminium and aluminium alloy enclosures and their welding. These enclosures are pressurized with dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor and outdoor installations of high-voltage switchgear and controlgear with rated voltages above 1 kV, where the gas is used principally for its…

1 Scope This Standard applies to wrought steel enclosures and their welding. These enclosures are pressurized with dry air, inert gases or gas mixtures (see Note 1) used in indoor or outdoor installations of highvoltage switchgear and controlgear, where the gas is used principally for its dielectric or arc-quenching properties, with rated voltages – of 1 kV and up to and including 52 kV,…

1 Scope This Standard applies to gas-filled welded composite enclosures of cast and wrought aluminium alloys pressurized with dry gases and gas mixtures (see Note 1) used in indoor or outdoor installations of highvoltage switchgear and controlgear, where the gas is used principally for its dielectric or arc-quenching properties, with rated voltages – of 1 kV and up to and including 52 kV,…

1 Scope 1.1 These requirements cover bare and covered ferrules intended for field wiring and factory wiring for use in accordance with the National Electrical Code, NFPA 70 and Canadian Electrical Code, Part I, CSA C22.1. 1.2 This standard applies to ferrules that are intended to facilitate the connection of stranded wire on to devices, such as terminal blocks. Their purpose is to treat…

This document provides a taxonomy to classify the type of adaptivity within vehicle systems. The taxonomy includes five types ranging from no adaptation (type 0) to adaptations based on interpreted user characteristics and context data (type 4). This document provides definitions of the five types of adaptation and explains adaptation in a consistent and coherent manner. By offering definitions…

Scope 1.1 These requirements cover electrically operated single and multiple station smoke alarms intended for open area protection in indoor locations and portable smoke alarms used as "travel" alarms in accordance with: a) In Canada: 1) Installation of Smoke Alarms, ULC 553; 2) National Building Code of Canada; and 3) National Fire Code of Canada. b) In the United States: 1)…

IEC/IEEE 63253-5713-8:2024 describes electrical and mechanical requirements of single-phase station service voltage transformers with system voltages of 46 kV or higher and with the maximum rated voltage of the power winding of 1 000 V. This document is a basis for the establishment of performance and limited electrical and mechanical interchangeability requirements of the equipment are…
