Abstract
A turbine engine includes an electrical system having at least two generator circuits, one coupled to a high pressure portion of a gas turbine engine and the other coupled to a low pressure portion of the gas turbine engine. The electrical system actively cools an electrical generator during operation in order to ensure proper operation as well as extend the lifespan of the generator.
