Quality assurance ensures electrical integrity, mechanical robustness, and long-term predictability. Line surge arresters go through many tests, including the residual voltage test, the lightning impulse withstand test, the switching impulse current test, the temporary overvoltage performance test, and the energy absorption capability test. Quality assurance must check the energy rating of the ZnO block, the quality of the porcelain or polymeric housing, the seal’s integrity against moisture ingress, and the corrosion resistance for coastal or desert environments. AI-supported infrastructure aspires for high availability and predictive maintenance. Surge arresters must show long-term durability through aging tests, salt fog testing, UV resistance testing, and thermal cycling. These tests confirm that performance parameters remain stable over operational life.
