In areas with frequent lightning activity, it is crucial to enhance the lightning protection effect of Three Phases AC SPD, because this is directly related to the safe and stable operation of the power system. Here are some recommended measures to enhance the lightning protection effectiveness of Three Phases AC SPD:
Reasonable selection: According to the local lightning activity and the characteristics of the power system, choose Three Phases AC SPD with large flow capacity, fast response speed and low residual voltage. Ensure that the selected lightning arrester can quickly absorb and discharge lightning energy and limit the damage to electrical equipment caused by lightning overvoltage and overcurrent.
Multi-level protection: Multi-level lightning protection measures are adopted, that is, different levels of lightning protection equipment are installed in the power system to form a multi-level protection system. This can discharge energy step by step when lightning waves invade, reducing the harm of lightning overvoltage to electrical equipment.
Optimize the grounding system: Ensure that the grounding resistance of the lightning arrester meets the specifications. Lowering the grounding resistance can improve the lightning protection effect. At the same time, conduct regular inspections and maintenance of the grounding system to ensure that the grounding system is in good condition.
Regular testing and maintenance: Perform performance testing and maintenance on Three Phases AC SPD regularly to ensure it is in good working condition. Lightning arresters with reduced performance or damage should be replaced or repaired in time to avoid a decrease in lightning protection capabilities.
Strengthen thunder and lightning monitoring and early warning: Use modern scientific and technological means to strengthen lightning monitoring and early warning work, and grasp dynamic information on lightning activities in a timely manner. Strengthen inspections and monitoring during periods of frequent lightning activity to promptly discover and deal with potential safety hazards.
Improve employee safety awareness and skills: Strengthen lightning protection safety education and training for power system employees, and improve employees’ safety awareness and operational skills. Enable employees to master the operation and maintenance methods of lightning protection equipment to ensure that they can respond quickly when lightning activities are frequent.
In summary, the lightning protection effect of Three Phases AC SPD can be effectively enhanced through reasonable selection, multi-level protection, optimized grounding system, regular testing and maintenance, strengthening lightning monitoring and early warning, and improving employee safety awareness and skills. Ensure the safe and stable operation of the power system.
