The vast majority of problems and breakdowns in the industrial environment–whether mechanical, electrical or manufacturing–are preceded by temperature changes that can be detected by temperature monitoring with the Infrared Thermal Vision system. The use of thermal imaging programs such as predictive maintenance in installations, machinery, electrical panels, etc. is possible to limit the risk of equipment failure and its consequences, while also offering a tool for quality control of repairs made.
Thermal imaging of electrical motors operates in their operating conditions through surface temperature. Ideally, motors should be checked when working under normal operating conditions. Unlike infrared thermometers that can only capture temperatures at a single point, a thermographic camera can simultaneously capture point mileage temperatures of all major components: the motor, the shaft coupling, the motor and shaft bearings, and the control box/connections. Most motors are equipped to operate at room temperature never exceeding 40ºC. In general, an increase of 10°C above the specified temperature reduces the service life of the engine by half.
By using thermography, electrical engineers can reap a number of benefits, one being analysis without stopping production processes. There is also low to no danger for the operator by avoiding the need for contact with the equipment, providing a safe, accurate test of your electrical elements. Infrared analysis also can provide an exact determination of deficient points in a process line, reduce repair time by accurately locating the fault, and provide very accurate reports to maintenance personnel.
In terms of preventative and predictive maintenance, it helps follow-ups on previous repairs and protection against inconveniences caused by the unexpected failure of an element via early detection. This works because a loose or corroded connection produces more heat due to increased resistance, which our thermographic cameras can detect during our inspections.
A system imbalance can be due to several reasons: a power supply problem, low voltage in one phase or a break in the insulation resistance of the motor coils. This causes motors and other loads to require more current, to have a lower torque (with the associated mechanical stress) and to break down sooner.
We offer full, detailed reports following our infrared analysis that fully details any issues we detect and recommended corrective actions. We craft our reports to fully describe our inspections and findings, giving you all the information you need to make a well-informed decision on repairs and maintenance.
Infrared analysis is one excellent tool that our company uses to build a full profile of your electrical components. If you are interested in our thermographic analysis, call us today to schedule your inspection.
