A New Detection Coil Capable of Performing Online Diagnosis of Excitation Winding Short-Circuits in Steam-Turbine Generators

Because excitation winding short-circuit faults that occur in steam-turbine generator will lead to heavy financial losses, accurately detecting excitation winding short-circuits (EWS) can help power generation operations. It can allow them to take timely actions and shorten downtime as well as cut t...
