MASTER CLASS – Power Transformer Insulation

The Australasian Transformer Innovation Centre (TIC) at the University of Queensland, will be hosting its first Master Class. Power transformers are the most expensive plant in a high voltage substation. The heart of a power transformer is the insulation. The insulation condition has major impact on the life and reliability of a power transformer. However, the material science of cellulosic insulation and insulation electric design principles are often the least understood area for those who specify, procure, operate, maintain and manage power transformers.

Aim of this Course

Drive your competitive advantage and enhance the performance of your transformer assets through:

✔ Practical industry led research that generates breakthrough innovations
✔ Ensuring you have the essential transformer skills for the future
✔ Having access to key knowledge that delivers tangible strategic benefits and savings.
