Abstract
Methods and apparatus that improve flashover voltage levels in turbine-generators, and reduce the spacing between the end portion connections of one phase group and the end portion connections of neighboring phase groups provide a semiconducting layer on the inside surfaces of insulation that surrounds such stator coil connections. At least one of the metallic connectors which join the end portions in each phase group is electrically coupled to this semiconducting layer, such that discharge between the metallic connector and the insulation surrounding its associated phase group are prevented.
