Deployment Practice of Smart Surge Protective Devices in Photovoltaic Power Station Monitoring

I. Lightning Protection Requirement Analysis for Photovoltaic Power Stations Photovoltaic power stations feature large footprints, module arrays exposed outdoors, long DC collection lines and complex grounding systems, making lightning protection a key factor in determining their operating life and power generation efficiency. According to GB 50057-2010 'Code for design protection of structures against lightning' and IEC 61643-11

Why Do Devices Still Get Damaged by Lightning After SPDs Are Installed?

I. What an SPD Protects Is Not the Device Itself, But a Discharge Path The function of an SPD is to conduct quickly when a surge voltage appears, limiting the overvoltage within the range the equipment can withstand and discharging part of the energy through the grounding system. So for an SPD to work, at least three things are required: the SPD itself must be in normal condition, the wiring must be standard, and the grounding
