Scope: In order to effectively control the AC interference corrosion hazards of the high-voltage AC transmission system and AC traction system on buried steel pipelines (hereinafter referred to as pipelines), reduce the impact of AC interference and lightning on the corrosion control system, and standardize the technical requirements for AC interference protection projects, develop this standard. This standard applies to the investigation and measurement of pipeline AC interference, and the design, construction and maintenance of AC interference corrosion protection projects. In the interference area, it is advisable to form an anti-interference coordination organization with representatives of the interfered party, the interference source party, and other relevant parties. According to the principles of unified testing, unified evaluation, and separate implementation and management, jointly fortify, coordinate, and handle to reduce interference . The technical requirements for AC interference protection of buried steel pipelines shall not only comply with this standard, but also comply with the current relevant national standards.
