Fault detection of contactor using acoustic monitoring

Abstract: Recently, condition monitoring methods using the sound of the machine have attracted attention. Since approaching high voltage equipment increases the risk of electrocuting, non-contact data acquisition is desirable. Most of the research targets of acoustic monitoring are rotating machines and it is not clear whether it is effective for machines that switch between two states, such as contactors and circuit breakers. In this work, several investigations have been carried out on the acoustic condition monitorin… Show more

“…Achieving this goal, therefore, requires using advanced analytics and maximizing not only the amount of data acquired but also the number of parameters monitored. Parameters that can provide indications of possible breakdowns can be captured with infrared thermography [24], acoustic monitoring [25], vibration analysis [26], oil analysis [27], and electrical analysis [28].…”
