To make the contribution for optimizing pollution test methods for porcelain-housed gapless metal-oxide surge arresters, artificial pollution tests have been conducted at a continuous operating voltage under various polluted conditions, using a two-unit type porcelain-housed gapless metal-oxide surge arrester for 154kV. In these tests, the leakage currents and quantities of electricity on the surfaces and through the elements of the arrester, the states of the dry band formation on the porcelain housing, the occurrences of partial arcs and the temperature rises of the elements are measured. This paper describes the test results and analyzed results of temperature rise of the elements under the artificial polluted conditions.
