Abstract :
The impulse level of high-voltage generator windings is reviewed with respect to the solid dielectric and gas spacing. Insulation differences between conventional and conductor-cooled generators are presented, industry application concepts are reveiwed, and proposals are made for a dc test that will assure a desired impulse strength level for generator windings.
