Transformer oil – e-lesson #13 – Copper corrosion

Event Details:
Live lesson is scheduled for March 6th at 2 pm CET at Transformers Academy.
This lesson provides an overview of copper corrosion in transformer oils, its causes, mechanisms, and mitigation techniques. It discusses the historical decrease in sulfur content in mineral oils and the paradoxical increase in corrosion issues. The lesson covers the evolution of oil refining technologies that enabled lower sulfur levels, as well as the potential role of modern transformer designs in exacerbating corrosion. It examines the standards for copper corrosion testing and the proposed mechanisms behind the issue. The presentation then delves into prevention methods, highlighting the importance of strict standard application and oil analysis. The primary mitigation technique of passivation is explained, along with its benefits and undesirable side effects. Finally, the lesson touches on other mitigation approaches, such as sulfur compound removal and oil reclamation, cautioning about potential pitfalls.
Here you can save your seat for the live or on-demand session.
The content of this lesson is fully vendor-agnostic, but it is sponsored by Ergon.
The lesson is conducted on the Mater’s level and after the live broadcasting, it stays available on demand. It is intended for utility engineers/chemists, transformer and oil manufacturers, students and faculty of educational institutes, oil testing laboratories, utility staff, etc.
The lesson #13 deals with copper corrosion, primarily its major causes, mechanisms and mitigation techniques.
