Innovations in T&D switching technology

René Peter Paul Smeets received a Ph.D degree for research work on switchgear in 1987.


Until 1995, he was an assistant professor at Eindhoven University. During 1991 he worked with Toshiba Corporation in Japan. In 1995, he joined KEMA, the Netherlands. At present, he is with KEMA Laboratories of DNV GL, as a service area and innovation leader. In 2001 he was appointed part-time professor at Eindhoven University, the Netherlands in the field of high-power switching and testing technology.

 In 2013 he became adjunct professor at Xi’an Jiaotong University, China.

 Dr. Smeets is convener/member of working groups and study/advisory committees of CIGRE in the field of emerging high-voltage equipment such as high-voltage vacuum -, HVDC switchgear and SF6 alternatives. He is member of CIGRE SC A3 for the Netherlands.

 He was convener of CIGRE A3.27 (high-voltage vacuum switchgear), was secretary of CIGRE WG A3B4.34 (HVDC switchgear) and at present he is convener of CIGRE WG A3.41 (impact of SF6 alternatives on switching).

As a workpackage leader in the EU Horizons 2020 project PROMOTioN (“Progress on meshed HVDC offshore transmission networks”) he is responsible for testing of various technologies of HVDC circuit breakers.

He is convener of two maintenance teams in IEC on high-voltage switchgear.

Dr. Smeets published and edited three books and authored over 300 international papers on testing and switching in power systems; in addition he conducted many tutorials and workshops all over the world.

In 2008 he was elected Fellow of IEEE and since 2008 he is chairman of the “Current Zero Club”, a scientific study committee on current interruption.

He received seven international awards, among which two from CIGRE.
