Health Monitoring of three phase induction motor using infrared thermography

摘要

In the current industrial scenario, three phase induction motors are mainly utilized as prime movers. Their collapse not only impact procedure downtime however additionally leads to manufacturing loss. On that account, its health monitoring is necessary as it expands its accessibility and efficiency. Infrared Thermal camera is a standard heat signature demonstrating instrument. As of up-to-date setting, infrared imaging is now fully grown and very popular technique for condition monitoring, using this temperature assessment are often directed progressively in non-contact way. Infrared diagnostic technique is employed as a method to differentiate variation from conventional range of temperature, small fluctuations within induction motor are applicable, however any uncommon change in temperature should be perceived, which can be an indication of excessive thermal stress and should be dealt with on time. Generally high temperatures harm the insulation of induction motor and in this way lessen its life expectancy. This paper traces a way to deal with detection of hotspot, thermal efficiency, remaining life and impact of temperature rise with time on induction motor which would help industries for predicting maintenance, preventing failures of induction motors.
