The authoe presents determination of parameters for the operating duty test of MOA for 1 000 kV AC system and relevant tests. Through the operating duty verification test on MOA for 1 000 kV AC system and its result evaluation, the rationality of selected parameters of MOA is validated. Studied by test, Maximum potential distribution coefficient of 1 000 kV arresters is 1.096 which is less than the specified value 1.15, and maximum current distribution coefficient is 3.45% which is less than the specified value 10%. Through operating duty test, the operating duty performance is meeting the technical requirements of 1 000 kV system.
