International Electrotechnical Vocabulary. Part 30 : Electric traction

This publication establishes a specialized vocabulary within the domain of electrical engineering, specifically dedicated to systems involving electric traction. It serves as a foundational reference for defining precise terms and definitions required to describe equipment, operations, and technical concepts associated with the propulsion of vehicles using electrical energy. The document aims to ensure uniformity in communication among engineers, manufacturers, and operators across various countries and industries. By providing a standardized set of technical terms, it facilitates clearer understanding in the design, maintenance, and regulation of electric railway, tramway, and trolleybus systems. This resource is widely utilized to avoid ambiguity in technical documentation, contracts, and safety guidelines. Its structure organizes terminology systematically to support global cooperation in the development of electrified transport infrastructure. The content covers a broad spectrum of vocabulary necessary for the accurate description of power supply systems, rolling stock, and associated control mechanisms. Adherence to these definitions promotes consistency in international projects and enhances safety through clear technical language.
