Cellulose papers and pressboards are widely used as insulators in power transformers and high voltage electrical equipment due of their good electrical properties, availability, and price. Critically, these materials must maintain both their mechanical and electrical properties at elevated temperatures in an oil filled environment for 30-40 years. With aging electrical equipment and ever-increasing energy demands, understanding cellulose degradation is a critical aspect in the manufacturing and maintenance of our electrical infrastructure.
Despite cellulose being used as electrical insulation for more than 100 years, its degradation under transformer operating conditions is not yet completely understood. Oxidative, acid-catalyzed hydrolysis, and thermal degradation all occur simultaneously over the lifetime of the transformer, each of which produce residues and water that cause corrosion and decreased mechanical and dielectric performance. This project aims to develop a deeper understanding of chemical and supramolecular structural changes that occur during cellulose degradation in power transformers, and to investigate modifications and/or additives that can increase the lifespan of electrical equipment.
This postdoc position provides a unique opportunity and environment as the candidate will work at both KTH, the Swedish research institutes RISE, and importantly in direct collaboration with the world leading provider of power transformers Hitachi Energy with access to their state of the art labs and equipment.
