Abstract

AbstractThe application of computer vision continues to widen with advancement in technology. Imaging systems which provide necessary inputs to the computer-vision-based models can come in various ways. Such as X-ray images, Computed Tomography (CT) scan images, and Infrared (IR) images. This paper is a review of different application areas of infrared thermography (IRT) for monitoring the status of electrical power equipment. It summarizes in tabular form recent research and relevant works within the field of condition monitoring of power assets. A general review of the application of IRT in power devices was undertaken before a specific review of selected works based on IRT for important electrical power equipment with a tabular review of possible causes of hotspots using photovoltaic installation as a reference. Results of previous works were presented with highlights on performance metrics used and accuracies achieved. Emphasis where made on the future potential of IRT and some associated techniques. The work saw that heat production within systems during operation is an important characteristic that enables IRT to become applicable for monitoring diverse physical systems, most importantly power systems. The high cost of high-definition, and long-range IR cameras limits the wide adoption of the technology for its potential applications for monitoring power installations. The work recommends future research in the development of affordable IR imaging systems with advanced features for condition monitoring of physical systems such as power installations.

Key Questions

What is the primary focus of the paper?

The paper focuses on the use of infrared thermography (IRT) for condition monitoring of electrical power equipment.

How does IRT contribute to power equipment monitoring?

IRT helps identify hotspots caused by faults in power equipment, which allows for early detection of potential failures, reducing downtime and enhancing efficiency.

What are the limitations of using IRT in power systems?

The high cost of high-definition and long-range IR cameras limits widespread adoption, making it challenging for some systems to implement this technology.

Which critical power equipment is monitored using IRT?

Power transformers, circuit breakers, and other electrical systems are monitored using IRT to ensure proper functioning and detect faults.

What are the potential future improvements for IRT in power systems?

Future research could focus on developing more affordable IR imaging systems with advanced features to enhance monitoring capabilities for electrical power systems.

What is the significance of heat detection in power systems?

Heat production within systems during operation helps IRT monitor the health of electrical components, as excessive heat indicates potential issues such as faults or wear.
