Abstract: Abstract:The grounding shortcircuit fault of the brushless exciter occurred due to coke powder pollution. Based on analysis of device structure, the parameters needing monitoring and adjusting during operation, such as temperature and insulation parameters, were proposed. Some measures, such as insulation maintenance and periodic dust removal, were adopted, and the brushless exciter operates normally. 
