Lifetime of Surge Protection Device Analysis and Monitoring

This article presents the service life analysis of surge protection device that uses a Raspberry Pi to manage data for equipment in an intelligent ground monitoring system. The system analyzes and validates the service life of surge protection devices (SPDs) based on the number of lightning strikes and the magnitude of current flowing through them. The system uses RS485 format data transmission to store information on a cloud database and uses SCADA software to display the status of the equipment in the system. The system also uses AC Class II SPDs for AC power and SPD DC Class II for DC power to estimate the service life of SPDs, enabling planning of operation, maintenance and enhancement of lightning protection performance and reliability. The article presents an evaluation of the service life of a SPD by analyzing the results of the relationship between the number of times and the magnitude of current flowing through it and compares it with data obtained from the SPD test according to the IEC 61643-11 standard.
