Applying Infrared Thermography for Monitoring the Condition and Failure Diagnosis of Power Network
, M.Sc. Thesis Sharif University of Technology ; Ghodrati, Behzad (Supervisor)
Abstract
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...
Feasibility Analysis of Backflow Detection in Lobe Blowers in Khuzestan Steel Plant using Condition Monitoring Techniques
, M.Sc. Thesis Sharif University of Technology ; Behzad, Mehdi (Supervisor) ; Mohammadi, Somayeh (Supervisor)
Abstract
Lobe blowers are positive displacement machines (PDM) that are widely used in various industries. The efficiency of lobe blowers depends on the clearance between fixed and moving parts. If the clearance between the parts increases, backflow occurs, which means that the flow returns from the high-pressure zone of the outlet to the low-pressure zone of the inlet, and this makes the blower not have the initial efficiency and work with a lower capacity than its design. This research is carried out with the aim of checking the feasibility of backflow detection using two condition monitoring methods, including ultrasonic and thermography techniques. The sample of this research includes seven...
Design and Implementation of Infrared Imaging Array and Image Processing using Machine Learning
, M.Sc. Thesis Sharif University of Technology ; Fakharzadeh, Mohammad (Supervisor)
Abstract
In this project, the physics of the thermal infrared spectrum was first studied, focusing on thermal modeling of hidden objects, and field experiments were conducted. Then, with the main goal of the project, which was to design and build an economical thermography system to be used as a complement to other scanners such as millimeter wave or X-ray, the main parameters of thermal infrared image detectors (FPA) available on the market were reviewed and the appropriate option was selected and purchased. In the next step, a comprehensive study was carried out on the specifications and performance of the selected sensor, and the image reconstruction mechanism was described and implemented in...
