Solar Radiation in Summer, Tank Surface Temperature and Leakage Current of SF6 Gas Insulated Type Surge Arresters for the 500kV, 1, 000kV power systems

Abstract

There is a few data of temperature characteristics of SF₆ gas tank type surge arresters. This paper describes the relation of solar radiation in summer, tank surface temperature and leakage current of SF₆ gas insulated type surge arresters for the 1, 000kV, 500kV power systems. The temperature of internal zinc oxide elements are evaluated as about 40°C.
