Electromagnetic interference (EMI) testing of electrical equipment

Assessment of the condition of electric machinery in a power plant has always been difficult. The standard on-line monitoring instrumentation is particularly deficient on generators. Specialized devices can be added to improve capability somewhat, e.g., generator condition monitor, flux probe for field turn shorts, stator endwinding vibration instrumentation, and partial discharge (PD) instrumentation.
