Hydrogen remains the cooling medium of choice for large turbine generators because of its superior heat-transfer efficiency and low windage losses. Yet that same efficiency creates a narrow safety margin. During outages or emergencies, operators must replace hydrogen with carbon dioxide and, if necessary, with air before personnel can enter the generator enclosure. Each transition
