ActiveArtificial pollution testing of non-linear resistor type gapped arresters
有间隙阀式避雷器人工污秽试验
Application Summary AI generated
This standard specifies the artificial pollution testing methods for non-linear resistor type gapped arresters, used to evaluate their insulation performance under contaminated conditions. It is applied in electrical power systems to simulate real-world pollution effects on high-voltage arresters, ensuring reliable operation in environments with dust, salt, or industrial pollutants. The standard is critical for manufacturers and testing laboratories conducting type tests or quality verification of arresters for transmission and distribution networks.
