We develop substation technologies to respond to the constraints of future DC networks as well as those of current AC networks. This includes using circuit breakers to clear fault currents from meshed DC networks, as well as developing interconnection nodes to transfer energy. Our circuit breaker technologies and protection strategies are designed to reduce the cost of infrastructure and preserve the stability and availability of the network.
Gas-insulated switchgear is essential to networks, yet it is currently highly dependent on sulphur hexafluoride gas (SF6) – at the top of the list of greenhouse gasses – as the insulating medium. We study, model and optimise alternatives for gas-insulated switchgear. In addition, we research and implement new solid and gas insulation systems to provide enhanced electrical performance and resilience whilst maintaining low environmental impact.
