Scope

Main technical content: This document specifies the basic requirements for the names and markings of relay protection equipment for power stations with voltages of 35kV and above, including device names and markings, auxiliary components' names and markings, and secondary circuit markings. This document applies to protection equipment and secondary circuits of all voltage levels in power stations with voltages of 35kV and above. For power stations with other voltage levels and DC converter stations, the requirements can be referenced for implementation. This document is primarily used to guide power grid enterprises, grid-connected power generation enterprises, and units responsible for the operation, maintenance, and management of relay protection equipment in user units. All units and departments involved in planning and design, research and manufacturing, installation and commissioning, dispatch management, and operation and maintenance should comply with this document.
