About the position

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? Are you interested in cable technology and condition monitoring, and do you have strong competence in signal processing and machine learning? 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 “Condition assessment of medium voltage cables based on pulse detection and machine learning.” You will join the research group High Voltage Technology at IEL, where we foster an open, inclusive, and collaborative working environment.

Our working environment is characterized 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 wrap up the week. These formal and informal occasions provide opportunities to exchange ideas, celebrate milestones, and strengthen connections. PhD candidates also arrange social activities, open to everyone who wishes to join, creating a welcoming and inclusive community.

Your immediate Line Manager will be the Head of Department.

The PhD position is funded by SecurEL.

About the project

About SecurEL

SecurEL is a Centre for Environment-friendly Energy Research, facilitating a secure, resilient, and sustainable electricity distribution grid that ensures both the security of electricity supply and a path to a net-zero-emissions society. SecurEL aims to develop new knowledge addressing research challenges arising from accelerated electrification and increased use of the existing grid. Reaching these goals requires strong interdisciplinary collaboration among research institutions, user partners, and experts with diverse areas of expertise.

The Centre brings together experts from fields such as electrical engineering, energy systems, information and communication technology, cybersecurity, engineering cybernetics, industrial economics, as well as humanities and social sciences, to develop effective solutions for the power grid. SecurEL is a consortium of 42 partners, including 7 research partners. The centre period is 2025-2032, and the total budget is 398 million Norwegian kroner (NOK). NTNU is represented as a partner mainly by the Department of Electric Energy (IEL) and the Department of Industrial Economics and Technology Management (IØT).

Recruitment and research education is an important part of the mission of SecurEL. The PhD candidates funded by the Centre will contribute with cutting-edge knowledge and research. Overall, the Centre will directly finance 17 PhD and postdoc positions, and also have several associated PhDs from closely related projects. As a SecurEL-funded PhD candidate, you will be employed by NTNU, a university partner in the Centre, and take active part in the research activities. Through the Centre, you will have access to a forum with other PhD candidates affiliated with the Centre, and opportunities for research stays with partners, both nationally and abroad, through its international network.

About the PhD position

Medium voltage extruded power cables are very important components in electricity distribution systems, especially in urban areas. Faults in distribution cable systems are rare but increase with service age and depend on the cable designs and environment. Because faults are generally costly to repair, methods that can precisely and rapidly locate faults or even faults under development are of great value.

Localization of very critical cable sections that are close to failure or other weak points where partial discharges have started can be made with advanced online detection methods. This includes both injection of high frequency signals and analysis of the response, or detection of current pulses generated by the weak spots in the cable section.

The PhD project consists of three parts: First, experimental studies of pulse propagation and its dependency on cable designs, materials and their condition. Second, simulation of pulse propagation in cables with variable parameters quantified in experimental studies. Third, utilizing signal processing and machine learning to develop detection and classification algorithms using measured and/or simulated data, such as current pulses from cable faults (breakdown), partial discharges and external noise.

In addition to being part of the research group High Voltage Technology, the PhD candidate will also work in close cooperation with SINTEF Energy Research and have access to first-class laboratories.

The main supervisor of the PhD candidate will be Professor Hans Kristian Høidalen (IEL). Co-supervisors will be Professor Øystein Hestad (IEL) and Senior Researcher Scientist Sverre Hvidsten (SINTEF Energy Research).

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 30 ECTS.
Contribute to publications in relevant journals and to popular science dissemination.
