    L2 TCA course – e-lesson #11: Infrared Thermography (IRT) applied to UHV power transformers and various substation components

    L2 TCA Course - e-lesson #11 - 850 x 400 illustration
    Course: Master’s level

    Hosted by: Jon Giesecke / Master's level

    In this lesson from the Transformers Academy, the presenter delivers an in-depth session on infrared thermography (IRT) applied to ultra-high voltage (UHV) power transformers and various substation components. The session offers a virtual tour through a substation, providing insights into analyzing components such as insulators, disconnects, arresters, bushings, and cooling systems. Participants will learn how to identify thermal anomalies that may indicate potential failures. Key concepts such as direct and indirect measurements, troubleshooting techniques, and interpreting thermal images to prevent equipment failures are also covered. This lesson is designed for thermographers seeking to expand their expertise in substation maintenance and component diagnostics using infrared technology.

    Over 30 years of IRT on substation components and oil filled power transformers will be presented in an easy-to-follow format. The presenter – Mr. Jon Giesecke – is a level III Infrared thermographer who has dedicated 57 years to learning about all forms of diagnostic tools and is ready to provide you and your team with his advanced knowledge.

    In this e-lesson you will learn how to diagnose many substation components and transformer problems using infrared thermography. You will also learn tips and tricks to doing a quality examination that can only be obtained by over 30 years’ experience.  Most of what will be presented is not found in any textbooks, so the value added by spending an hour with the author is priceless.  There will be a Q&A session directly following the presentation.
