Premier providers of quality thermal imaging solutions
Above: This is an image of a Contactor obtained during a recent survey. With a temperature of 146.3 degrees it clearly shows a problem on the Centre phase. This was almost 50 degrees above the other two phases. Further investigation revealed a loose connection which had caused oxidization of part of the cable.
Above: This image shows a hot spot with a temperature of 231 degrees. The load on all three phases is almost the same, and it was possible to calculate that the temperature on full load would rise to 774 degrees.The fuse unit was found to be faulty and was replaced at the first possible opportunity. If left this item would almost certainly have caused a fire, and shutdown the entire factory.
With more than 15 years experience in the electrical industry we feel that we are in a unique position in this field. Our knowledge in electrical installations includes everything from hotels to hazardous areas. Typical candidates for an infrared electrical survey include overhead transmission lines, substations, transformers, thyristor banks, circuit operating devices, switches, fuses, circuit breakers, control equipment, motors and motor control centers.
The image below is of the connections on the heating elements of a furnace. There is a problem with the refractory lining on the top of the furnace which is allowing the heat to rise and this is causing the connections to rise well above three hundred degrees.
