Scope
This standard specifies the performance requirements of the entire protection system and its components. This standard applies to protective devices in protection systems and devices connected to protective devices that affect their performance. This standard applies to the following objects: - manufacturers of protective systems or their components; - users of protective systems; - manufacturers of control panels; - electrical equipment installers; - consultant engineers. Various IEC standards specify the technical requirements for the various components of the protection system, and these standards are referenced in the relevant parts of this standard. Appendix A lists a block diagram of a protection system, which also shows the relevant IEC technical committees that develop technical specifications for the various components of the protection system. The user is advised to make decisions consistent with the provisions of the technical committees involved, which are responsible for the overall protection system.
