A 3-phase, 60 Hz star-connected (Y-connected) alternator generates an RMS line-to-line voltage of 23,900 V. Calculate its peak line voltage.

Which design feature is primarily associated with the rotor of a high-speed turbo-alternator to handle centrifugal forces and minimize windage losses?

In a Doubly-Fed Induction Generator (DFIG) used for variable speed wind energy conversion, the stator is connected to the ________ supply and the rotor is connected to the ________ supply.
