Zusammenfassung:This paper describes the theory, development history, and application of electromagnetic interference diagnostics for the condition assessment of high-voltage apparatus such as motors, generators, transformers, switchgear, and bus. Data are collected while equipment remains in service. Examples of common problems identified at power facilities, upstream off shore production rigs as well as downstream, plastics, chemical, and central utility facilities are provided. How data are collected, analyzed, and presented is discussed.
