High Temperature Insulation Systems: An Option for Resilient Transformers

The article reviews the newest developments and trends towards large power transformers for improving grid resiliency by using advance insulation systems allowing for smaller size, lower weight designs. Initially developed for mobile transformers and substations, the hybrid insulation system have to evolve to allow for larger units to be transformed easily and rapidly to areas with emergency situations. To achieve such compact designs, insulation systems have to be developed with new insulation components made out of high temperature materials.
