What is BS IEC 1000-5-4 - Protective devices about?
BS IEC 1000 is a series on Electromagnetic compatibility (EMC). The goal of Electromagnetic compatibility is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering. BS IEC 1000-5-4 defines how protective devices for High Altitude Nuclear Electromagnetic Pulse (HEMP) protection of civilian systems are specified. Performance requirements will be given in future IEC standards.
BS IEC 1000-5-4 is intended to be used for the harmonization of existing or future specifications issued by protective devices manufacturers, electronic equipment manufacturers, administrative bodies, and other buyers. BS IEC 1000-5-4covers protective devices currently used for protection against HEMP radiated EM fields. In general, parameters relevant to HEMP, that is parameters related to very fast changes of EM fields, as a function of time, are dealt with.
Who is BS IEC 1000-5-4 - Protective devices for?
BS IEC 1000-5-4 on protective devices is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS IEC 1000-5-4 - Protective devices?
Electromagnetic compatibility is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage to operational equipment. Both mechanical and electrical design aspects should be considered in order to specify protection devices.
Specifications of BS IEC 1000-5-4 include a general description (presentation, purpose), application information (specific use), material description (material, consistency, colour, finish, etc.), and performance characteristics (E, H and plane wave attenuation, d.c. resistance, temperature range, mechanical properties, transfer impedance and if necessary, transfer admittance), dimensions, recommendations for use (surface preparation, pressure, safety and operational cautions), methods of construction, mounting techniques (way of assembly) and storage recommendations. Using BS IEC 1000-5-4 you can define how protective devices for High Altitude Nuclear Electromagnetic Pulse protection of civilian systems are specified.
