ETH Zürich is offering PhD positions in high-voltage circuit breaker technology, focusing on the development and optimization of environmentally friendly alternatives to SF6 gas in high-voltage switchgear. SF6, currently the most widely used gas in this field, has a global warming potential 23,500 times higher than CO2, making the search for sustainable solutions urgent and globally relevant. Successful candidates will conduct mostly experimental research on the arcing behavior and current-interruption capabilities of novel non-SF6 gas mixtures. The research is based in the high-voltage laboratory, which emphasizes a strong experimental approach, including the planning, design, construction, commissioning, and automation of novel setups and voltage/current sources tailored to specific research questions. Data collected is analyzed using state-of-the-art theoretical models and published open access. The overarching goal is to advance the fundamental understanding of electrical insulation and current interruption, contributing to the development of innovative engineering solutions for the energy sector. The laboratory collaborates closely with leading manufacturers in power transmission and distribution equipment, and the research team is composed of members with interdisciplinary master’s degrees. ETH Zürich values diversity, sustainability, and an inclusive culture, promoting equality of opportunity and a climate-neutral future. Applicants should have a degree in electrical engineering, mechanical engineering, physics, or a related field from a top-tier university, with an excellent academic record. Motivation, independence, organizational skills, and the ability to present results are essential. Prior hands-on experience, such as conducting scientific experiments or participating in competitive student teams, is required; prior experience in high-voltage engineering is advantageous but not mandatory. Application materials include a letter of motivation, CV, transcripts, and two references, with letters of recommendation optional at this stage. Applications must be submitted online via the ETH Zurich portal; email or postal applications will not be considered. For further information, candidates may contact Prof. Christian Franck ([email protected]) with questions about the position (not for applications).

ETH Zürich, a world-leading university in science and technology, is offering a postdoctoral position in high-voltage insulation systems within its High Voltage Laboratory. The research group focuses on understanding the effects of high electric field strengths and voltages, with a strong emphasis on experimental work. Researchers in the lab plan, design, construct, and automate novel setups and voltage/current sources to address key research questions, and analyze measured data using advanced theoretical models. The overarching goal is to advance the fundamental understanding of electrical insulation, particularly in the context of the ongoing transformation of the global energy system toward renewables and improved efficiency. The successful candidate will work both experimentally and theoretically to investigate the aging of solid insulation under mixed-frequency medium-voltage stress, contributing to the development of novel engineering solutions for power transmission and distribution equipment. The team collaborates closely with leading manufacturers and is composed of researchers with interdisciplinary backgrounds. Applicants must hold a doctoral degree in electrical or mechanical engineering, physics, or a related field, and have a strong academic record. Prior experience in high-voltage engineering, especially with solid insulation systems, and hands-on experimental work is required. The position offers the opportunity to work in a diverse, inclusive, and sustainability-focused environment at ETH Zürich. Application materials include a letter of motivation, CV, transcripts, a single best publication, and a letter of recommendation. Applications must be submitted online; email or postal applications will not be considered.
