PhD student position in Electrical discharges - Hiring in process/Finished, not possible to apply

This call is for a PhD student who can contribute to the field of electrical discharges in the atmosphere. The position is at the Division of Electricity, the Department of Electrical Engineering, at the Ångström laboratory. For more information, please visit our webpage. 

The Department of Electrical Engineering is an international environment with approximately 130 employees at Ångström Laboratory. The Department conducts research and teaching in Electricity, Solid State Electronics and Signals and Systems.

Project description: The actual atmosphere in which electrical apparatuses will be used and tested is often different from the so-called standard atmosphere. Therefore, conversion factors for dielectric strength of electrical apparatuses at different atmospheric conditions are necessary in the design of high voltage apparatus. A procedure for estimating such conversion factors has been standardized in IEC 60060. The procedure presented in IEC 60060 was obtained after significant simplifications and rough generalization of the test results from different electrode arrangements exposed to different atmospheric conditions. However, the laboratory experiments could not cover all possible electrode configurations and atmospheric conditions that are needed in high voltage applications. Thus, a detailed understanding of the physics of electrical discharges at different pressures, temperatures and humidity conditions are needed in order to describe fully the breakdown phenomena and dielectric strength of air at extreme low up to high humidity. The goal of this research project is to study theoretically the effect of humidity on electrical discharges, taking into account the physical mechanisms of electron avalanches, streamers and leaders. In order to support the theory to be developed, some experiments in the high voltage laboratory are also required.

Duties: The work will mainly be carried out by FEM-based multiphysics simulations, but also includes some experiments at the high voltage laboratory at Uppsala University. The main duties of the doctoral student are to devote herself/himself to her/his research studies, which include participating in research projects and third cycle courses. The work duties also include teaching and other departmental duties (no more than 20 %).

Requirements:

• An undergraduate degree or equivalent in electrical engineering or engineering physics.
• Very good oral and written proficiency in English.
• A strong motivation and ability to work individually.

Additional qualifications:

• Since the duties of PhD students include certain amounts of teaching, experience in teaching at a university is a merit.

Application: Please use the link below. You should include a brief description of your research interests and relevant experience, a CV, copies of diplomas and certificates, thesis (or a draft thereof) and other relevant documents. You are encouraged to provide letter(s) of recommendation and/or the contact information of the referees.

Rules governing PhD students are set out in the Higher Education Ordinance chapter 5, §§ 1-7 and in Uppsala University's rules and guidelines http://regler.uu.se/?languageId=1.

Salary: According to local agreement for PhD students.
 
Starting date: 2021-01-15 or as otherwise agreed.

Type of employment: Temporary position according to the Higher Education Ordinance chapter 5 § 7.

Scope of employment: 100 %
