摘要
Abstract
This paper adopts State Power from South DGT801U series protection device of injection type stator grounding protection test are analyzed in detail.Combined with the test process of injection stator grounding protection of 660MW generator, the field wiring configuration, the protection principle, the protection criterion and the setting method are analyzed.And through the calculation and example analysis of the sensitivity of the protection device, verify the used in the test of DGT801U series of stator grounding protection device has the advantages of high measuring accuracy, enough to meet the engineering requirements of injection type stator grounding protection sensitivity.关键词
