? More big news from the 2025 Industry Navigator conference in Dubai!! ? I'm delighted to announce that Essex Energy | Essex Italy S.r.l. is joining us again as a Champion for the next Industry Navigator conference 'Sustainable Development Strategies for T&D', taking place at the prestigious Raffles Hotel in Dubai from 9-11 April 2025. This business-oriented conference, powered by Transformers Magazine and Switchgear Magazine, is focused on the major industry challenges. The Industry Navigator initiative includes a number of impactful programmes, including in-depth #research, the Transformers Magazine #Quiz League, and, of course, our flagship #conference. Links to these programmes are available in the comments. This is the second time that Essex Energy | Essex Italy S.r.l. has supported these initiatives as a Champion. As a conductor supplier, their support in the work of the Transformer Champions Club think tank has been invaluable, as the Essex team have particularly enriched our insights into ways to improve automation in the industry. The link to the Essex presentation from the last conference in Madrid is in the comments. Research & Insights: sponsorship of Industry Navigator research projects enables deep industry insights, often leading to trend analysis that wouldn’t otherwise be available. As such, they influence industry practices worldwide for years to come. Our latest report was used by the European Commission as a reference document for the European Union's new energy #strategy. Our new research is focused on the #workforce challenges. This time participation in the research is possible only by invitation, so if you would like to participate and you haven’t received invitation, feel free to contact us. A sincere thank you to the entire Essex team for their invaluable contributions! Why participate? Joining us at the conference or participating in our research initiatives, you have a direct impact on the future of the T&D industry. Take part in our survey, and ensure your unique insights are part of this influential dataset. And get involved in our Quiz League, where we work with partners to promote excellence and attract young talent to our industry.

?? Join us for the final lesson of The introduction to Transformers course at Transformers Academy! The content of this lesson is fully vendor agnostic but thanks to our sponsor The H-J Family of Companies it is available for free to everyone! This lesson's author, mr. Orlando Giraldo will delve into critical aspects of transformer life and operational stability, making it invaluable for professionals in the field! ? Join us and register on the link: https://lnkd.in/dkupVjws ?? Key topics covered include: ? ?????????????????????? ?????????????? ??????????: The lesson introduces the mathematical model that describes how heat affects transformer performance. This model is essential for predicting transformer behavior under various loads and temperatures. ? ???????????????????? ?????? ????????????????: Temperature management is crucial for transformer insulation and longevity. This section examines factors that cause insulation degradation, such as temperature, time, humidity, and oxygen levels. Attendees will learn how these factors impact mechanical and dielectric strength, which are central to transformer reliability?and expected life. ? ???????? ???????????????? ????????????????????: The course explains conduction, convection, and radiation in the context of transformers. Understanding these mechanisms is essential for assessing and improving cooling systems and overall transformer efficiency. ? ?????????????????????? ???????????? ?????? ?????????????? ??????????????: The lesson reviews acceptable temperature ranges and highlights the design and function of different cooling systems. Participants will learn about the significance of the “hotspot” temperature, which directly affects a transformer’s life expectancy. ? ?????????????? ???????????????????? ?????? ???????? ????????????????????: Engineers will gain insights into optimal transformer loading under various conditions, including adjustments based on ambient temperature and altitude. The lesson also covers the Heat Run Test, which assesses the main temperatures in a transformer under full load and provides essential data for load and temperature modeling. This lesson is perfect for engineers looking to deepen their understanding of transformer management and preventive maintenance, and it serves as an excellent lead-in to advanced diagnostics and operational strategies in transformer engineering. #heattransfer #insulation #transformers #transformersacademy #knowledgeplatform ?
