Abstract:
A method for inspecting a wye ring in a generator includes the steps of dismantling the generator to gain access to the wye ring and at least a portion of a rotor, applying a test signal to the rotor and measuring an inductive voltage at two or more locations near the wye ring. A comparing step compares results from the measuring step to determine if a fault exists in the wye ring. A predetermined difference in inductive voltage measurements indicates presence of the fault.
