The results show that equipment failure signatures have diverse characteristics in terms of time scales and patterns. The signatures are visible in both voltage and current waveforms and they exhibit a wide variety of characteristics.<\/p><p>The reports reveals how methods developed for detecting power quality disturbances are not adequate to capture equipment failure related disturbances. Importantly, the report also discussed the research needs in the area of disturbance signature analysis for equipment condition monitoring.\u00a0 A general-purpose condition monitoring system is considered involving several steps:<\/p><ol><li>The first step is to detect the existence of waveform abnormality.<\/li><li>The second step is to extract the waveforms associated with the abnormality.<\/li><li>The third step is to analyse the extracted waveforms to determine the cause of abnormality and if equipment failure is involved.<\/li><li>The fourth step is to determine the characteristics of equipment failure such as the location of an incipient fault.<\/li><\/ol><p><em><img loading=\"lazy\" class=\" wp-image-659 alignright\" src=\"https:\/\/engineeringimpact.co.uk\/wp-content\/uploads\/2021\/02\/IEEE_PES_Logo-300x157.jpg\" sizes=\"(max-width: 328px) 100vw, 328px\" srcset=\"https:\/\/engineeringimpact.co.uk\/wp-content\/uploads\/2021\/02\/IEEE_PES_Logo-300x157.jpg 300w, https:\/\/engineeringimpact.co.uk\/wp-content\/uploads\/2021\/02\/IEEE_PES_Logo-1024x535.jpg 1024w, https:\/\/engineeringimpact.co.uk\/wp-content\/uploads\/2021\/02\/IEEE_PES_Logo-768x401.jpg 768w, https:\/\/engineeringimpact.co.uk\/wp-content\/uploads\/2021\/02\/IEEE_PES_Logo.jpg 1200w\" alt=\"\" width=\"328\" height=\"172\" \/><\/em>In summary, Dr Todeschini comments:<\/p><p><em>The report confirmed it is possible to identify abnormal equipment behaviour by monitoring voltage and current waveforms and developing appropriate algorithms to process these waveforms.
