We focus on High Voltage Direct Current substation equipment, addressing the many challenges involved in these technologies. For example, studying a circuit breaker’s ability to interrupt fault currents within a meshed DC network is an essential question. We develop technologies associated with protection strategies that enable reduced infrastructure costs while maintaining the stability and availability of the networks.
Gas-insulated substations for DC applications are an essential part of future DC networks. Our research focuses on understanding, modelling and optimising the insulation systems used in substation component design. Disconnector performance, earthing switches and transformers must also be adapted to meet the operating constraints of DC networks.
In our research, we also focus specially on developing and integrating new solid and gas insulation systems which provide enhanced electrical performance and resilience, enabling us to develop interruption principles that have a low environmental impact
