Recently, the company launched a pre test for lightning protection in the spring of 2015, laying a solid foundation for promoting the safe operation of the power grid.

The main task of this work is to conduct live testing on the lightning arrester of the substation and test the grounding resistance of the substation. At the same time, a retest diagnosis was conducted on the "problematic" lightning arrester discovered in 2014. As a part of the spring inspection work, the company attaches great importance to it and is fully committed to ensuring the smooth progress of lightning protection pre testing work in various aspects.

It is understood that the staff has maintained the testing instruments in advance, verified the safety insulation tools and testing instrument tools, and ensured the accuracy and reliability of the monitoring tools. The professional department provides on-site testing training for personnel participating in lightning protection pre testing work, providing timely training and guidance on pre work division, safety measures, meter wiring judgment, and selection of grounding conduction testing points to ensure the quality and efficiency of lightning protection pre testing work. Each professional team holds a pre shift meeting to familiarize themselves with the relevant regulations on live detection, analyze hazardous points, and develop pre control measures. Maintain sufficient safety distance from live equipment during operation, prevent accidental contact with live equipment, strictly follow standardized procedures, and ensure safe and standardized testing work. At the work site, safety management personnel or safety specialists are in place to manage. Strictly implement the company's 2015 lightning protection work plan, implement "dangerous point" prevention and control measures, strengthen full process monitoring and supervision, and ensure implementation is in place. In addition, the company is actively exploring new work projects for live detection to improve quality and efficiency, reduce the frequency of power outages, enhance power supply reliability, increase electricity efficiency, and contribute to the comfortable use of electricity by users.
