About the position
Are you motivated to take a step towards a doctorate and open up exciting career opportunities? Do you have a background in high voltage engineering, and are you interested in gas insulation systems? As a PhD candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.
The Department of Electric Energy (IEL) at NTNU is seeking a highly motivated candidate for a full-time (100%) PhD position for 3 years as part of the project “NEMEGIS”. You will join the research group High Voltage Technology at IEL, where we foster an open, inclusive, and collaborative working environment.
Our work environment is defined by its friendly and supportive atmosphere, with regular gatherings such as professional meetings within the research group, weekly colloquia, shared lunches, and “Friday coffee” sessions to end the week. These formal and informal events offer opportunities to share ideas, celebrate milestones, and build relationships. PhD candidates also organize social activities open to everyone interested, fostering a welcoming and inclusive community.
Your immediate Line Manager will be the Head of Department.
About the project
During the green transition, DSOs and TSOs are expanding and maintaining power grids to meet rising electricity demand while ensuring supply security. Switchgear, crucial for rerouting energy and interrupting faults, traditionally uses SF₆ gas—an extremely potent greenhouse gas with a GWP of 24,300 and a lifetime of ~3,200 years. EU regulations now mandate SF₆-free switchgear: from 2026 for ≤24 kV and from 2028 for ≤145 kV. This requires new technologies, as SF₆ alternatives (e.g., N₂, O₂, CO₂ mixtures) demand higher pressures and reinforced designs. Manufacturers face major redesign challenges, especially for high-voltage ratings under extreme fault conditions. Scientifically, optimizing new gas mixtures is complex, with gaps such as missing photoionization data. The NEMEGIS project aims to fill these gaps by studying insulation properties, long-term performance, and sharing knowledge to support manufacturers, grid operators, and researchers. In this project, one PhD position with a focus on Partial discharge ageing and memory effects in new gases is available, where the main research questions are:
- How do the AC and LI PD properties change over time for relevant defects in the new gas mixtures and what differences exist between the gas mixtures?
- To what extent can knowledge from known PD behaviour in SF6 gas be applied to PD in the new gases?
- What is the effect of gas decomposition products such as ozone and CO on PD behaviour?
- Can the experimentally observed PD properties, decomposition products and memory and ageing effects be explained using known theory and computational models?
The main supervisor will be Professor Frank Mauseth, with Nina Støa-Aanensen and Hans Krisitan Meyer as co-supervisors.
Duties of the position
- Carry out research of high quality within the framework described above
- Participate in activities of the research group High Voltage Technology (HVT)
- Complete academic training consisting of coursework corresponding to a minimum of 30 ECTS
- Contribute to publications in relevant journals and to popular science dissemination
- Participate in international activities such as conferences and/or research stays at foreign educational institutions
Career-enhancing work, which is in addition to the research project and doctoral education, may be offered to a candidate who demonstrates clear motivation and ability for such work, and if the Department determines there is a need. Examples of career-enhancing work include, but are not limited to, contributing to teaching, laboratory and exercise teaching, supervision, and examination work within the employee's areas of competence.
Be prepared for changes to your work duties after employment.
