4 How to use thermography for electrical equipment?

To use thermography for diagnosing electrical equipment, power engineers should take some basic steps. This includes preparing the equipment and environment, selecting the appropriate camera and settings, capturing thermal images, and analyzing and reporting the results. Before beginning, make sure the equipment is under normal load and operating conditions. Additionally, remove any covers, shields, or barriers that could block infrared radiation. Then choose an infrared camera with a suitable resolution, sensitivity, and range for the equipment and distance. Adjust the focus, emissivity, and temperature scale to match the characteristics of the components and environment. After this, scan the equipment from different angles and distances to cover all relevant parts. Compare images with baseline data or reference standards to identify anomalies or deviations. Record images and associated data for further analysis. Use software or tools to process and enhance thermal images. Classify problems according to severity and urgency. Recommend appropriate actions or solutions to correct or prevent problems. Document and communicate results to relevant stakeholders.

5 What are some best practices and tips for thermography for electrical equipment?

To use thermography for diagnosing electrical equipment effectively and efficiently, power engineers should adhere to some best practices and tips. Regular and systematic inspections should be planned and scheduled according to the manufacturer's guidelines, industry standards, and company policies. Coordination with the maintenance team, operators, and managers is necessary to ensure the availability and safety of equipment and personnel. Operators must be trained and certified in order to have the required knowledge, skills, and qualifications to use infrared cameras and interpret thermal images. Certification programs and codes of ethics of professional associations or regulatory bodies should be followed for thermography. Thermography should be used as part of a comprehensive maintenance program that combines it with other testing methods and techniques for a complete and reliable diagnosis of electrical equipment. It should also be used as a preventive or predictive maintenance tool rather than a reactive or corrective one.
