The project will involve the study of Gas insulated substation to gain in-depth understanding of phenomena appearing in gas insulated systems. These will include discharge activity, transient over outages during disconnect or switching and line closing when connecting to overhead line circuits. Furthermore earthing scenarios will be investigated to determine the need and requirements for high frequency earthing in such systems, safety aspects of such configurations will be evaluated. The models generated within the modelling and simulation task will be compared and verified with controlled experiments and onsite testing. For the purpose of advanced measurements, new fast voltage transducers will be designed, built and tested to allow measurement of the fast transient over outages.The project will identify the most promising applications for graphine and other 2D materials in electrical transmission systems and examine the feasibility of using these materials on the transmission system. The project will consider the likely financial benefits, likely time to market, specific application issues, and recommend the pathway to deployment.

该项目将涉及气体绝缘变电站的研究，以深入了解气体绝缘系统中出现的现象。这些将包括放电活动、断开或切换期间的瞬时断电以及连接到架空线路电路时的线路闭合。此外，还将调查接地情况，以确定此类系统中高频接地的需要和要求，并将评估此类配置的安全性。建模和模拟任务中生成的模型将通过受控实验和现场测试进行比较和验证。为了进行先进的测量，将设计、制造和测试新的快速电压传感器，以测量快速瞬变过断电。该项目将确定石墨烯和其他2D材料在电力传输系统中最有前途的应用，并研究在传输系统中使用这些材料的可行性。该项目将考虑可能的财务收益、可能的上市时间、特定的应用程序问题，并推荐部署途径。
