DUBAK ELECTRICAL UTILIZES INFRARED IMAGING SYSTEMS WITH POWERFUL SOFTWARE TO PROVIDE A FAST AND EFFECTIVE MEANS OF IDENTIFYING POTENTIAL PROBLEMS IN ELECTRICAL AND MECHANICAL EQUIPMENT, REFRACTORY AND INSULATION MATERIALS. THIS INFORMATION IS COMPILED INTO A COMPREHENSIVE REPORT USING EASILY INTERPRETED TEXT WITH THE INFRARED IMAGE AND A VISIBLE LIGHT REFERENCE. PREVENTIVE OR CORRECTIVE REPAIRS CAN THEN BE SCHEDULED ON A PRIORITY BASIS.
Infrared thermography is an effective means to identify excessive heat loss in systems or materials.
Every object radiates electromagnetic energy invisible to the human eye, but visible to specialized equipment. Thermal imaging radiometers can detect and measure infrared radiation, and produce a map – whether of colors or varying shades of gray – that show the surface temperatures of the object. The lighter colors or shades represent the warmest temperatures and the darker colors or shades the coolest. By analyzing the temperature signatures of equipment, problem areas are quickly identified and recorded along with all of the related temperature information.
Thermography was first utilized in the inspection of electrical equipment to locate high resistance connections or faulty components. It has also been proven in finding areas of reduced insulation in buildings and refractory materials, and even leaks in building roofs.
Inspection of rotating machinery is a way in which thermography is now being used more extensively. It has been found effective in identifying faults in bearings, couplings, and shorts in motor cores.
