Insulation problems in high voltage machines

Insulation problems in high voltage machines

The insulation of high voltage coils of rotating electrical machines experiences multiple stresses due to mechanical, electrical and thermal conditions. A slot model was built to simulate actual conditions. The sources of these stresses and recommendations to relieve their effects are discussed.<...
