Renewable Insulation Liquids for Transformers
Turning electrical assets into green machines
BY RONNY FRITSCHE & GEORG PUKEL, Siemens AG
Transformers are one of the most important components of energy grid systems. They enable the efficient transport of electric energy from the location where the energy is generated to the location where the energy is needed. Transformers, especially power transformers, are conventional electric equipment based on physic concepts and materials developed decades ago, making it critical to implement new designs and...
