Editorial: What is the future for transformer insulation?

The 2020s are going to be an exciting decade of change in terms of how people interact with the electricity grid. In Australia and New Zealand, the electricity systems are decarbonizing, driven by economics and government policies. New technologies such as rooftop PV, solar, and wind are entering the system.
