  7. Abstract:
  8. Temperature and the resulting thermal behavior of electric power generation and distribution equipment and industrial electrical systems and processes are the most critical factors in the reliability of any operation or facility. Temperature is by far the most measured quantity in any industrial environment. For these reasons, monitoring the thermal operating condition of electrical and electromechanical equipment is considered to be a key factor to increasing operational reliability. Infrared thermography (IR/T) as a condition monitoring technique is used to remotely gather thermal information for monitoring the condition of virtually all of the electrical components on an entire system and from generation to end user. Once the baseline is established, IR/T will reveal the thermal variances deviating from the norm. This localized thermal deviation can either be caused by an overheated condition or absence of heat. The information is reviewed and decisions are made for repair, or to plot the temperature change over time and repair the component at a more opportune time. The information can be stored and fully analyzed at a later date providing complete computer-aided predictive maintenance capabilities and trending. Infrared Thermography is currently experiencing rapid growth as more and more electric utilities and industrial sectors are embracing the technology. During this Thesis we have tried to introduce this technique to Tehran’s electrical power distribution system. Our activities initiated with convincing the managers to implement this technique and organization thermography activities. During this period we had completed thermal imaging of 20 electric posts out of 500 obliged in the contract. Integrated table and thermography reports formatting fulfilled by our team was the most important achievements of our thesis. After all like many other projects done in Iranian industrial culture, we had many managerial and technical problems
