Compliance overview
Scope and applicability
This standard specifies the basic electrical safety requirements for power production units and personnel working in power production sites. It is applicable to operating electrical equipment and related sites of power generation enterprises with facilities of 66kV and above, transmission, substation, and distribution enterprises with facilities of 35kV and above, and power consumption units with facilities of 220kV and above. Other power enterprises and power consumption units may also refer to this standard for safety compliance.
Technical requirements
The standard outlines comprehensive safety protocols for electric power line operations, covering personnel qualifications, site conditions, and operational measures. It mandates specific safety organizational measures, including the use of various work tickets (e.g., First Kind Work Ticket, Second Kind Work Ticket), work permits, supervision, and work conclusion procedures to ensure a systematic approach to hazard prevention. Furthermore, it details safety technical measures that must be implemented before and during operations. These include strict procedures for power outages, voltage verification, installation of grounding lines and personal security lines, and the proper placement of warning signs and barriers. The standard also provides specific safety distance requirements between workers and live parts under various voltage levels. The standard extensively covers operational guidelines for line maintenance, work near live conductors, and specific tasks such as high-altitude operations, tower construction, and stringing. It also sets forth specialized requirements for live working and power cable work, emphasizing environmental safety, tool usage, and emergency protocols. Appendix E specifically regulates the testing items, cycles, and requirements for insulated safety tools.
Testing methods
The standard includes an appendix detailing the testing methods and cycles for insulated safety tools. Key tests involve the starting voltage test and power frequency withstand voltage test for capacitive voltage detectors and insulating rods. It also specifies DC resistance tests for portable grounding lines and personal security lines, as well as leakage current tests for insulating boots and gloves to ensure the integrity of personal protective equipment (PPE).
FAQs
