Electromagnetic-interference (EMI) diagnostics is defined as the precise measurement and analysis of conducted and radiated signals produced by electrical and mechanical defects in high-voltage systems.
The industry faces challenges where too much emphasis is placed on engineers in the field being able to identify key frequencies by eye or knowledge alone. This will limit the ability to automate the process. Automated identification of insulation faults, using EMI methods, are the best solution to monitor electrical equipment. Applying a reliable, non-invasive surveillance technique will provide the best, most accurate test results.
