KEMA Labs paper won the prestigious Wang Jimei Best Paper Award
25 . Mar . 2022

Authored by KEMA Labs experts Nadew A. Belda (Innovation Engineer), René P. P. Smeets (KEMA Labs Advisor) and Roy M. Nijman (Test Engineer), the KEMA Labs’ IEEE journal paper , Experimental Investigation of Electrical Stresses on the Main Components of HVDC Circuit Breakers , has won the prestigious Wang Jimei Best Paper Award .

Experimental Investigation of Electrical Stresses on the Main Components of HVDC Circuit Breakers provides useful insights on the stresses of HVDC circuit breaker internal components through experimental investigation. The result of this experimental investigation is serving as an important input to ongoing international standardization activities related to the HVDC circuit breakers. The work of the paper was conducted at KEMA Labs high-power laboratory in Arnhem, The Netherlands , within the framework of the recently concluded EU funded PROMOTioN (Progress on Meshed Offshore Transmission Networks) project .

The award is given for the best, most significant presentation during the 6th International Conference on Electric Power Equipment – Switching Technology 2022 (6th ICEPE-ST 2022) , which aims to provide opportunities for researchers and engineers from around the world to present their works and share their ideas in the field of Electric Power Equipment – Switching Technology. In particular, the award is given to the best peer-reviewed extended paper based on an ICEPE-ST 2019 contribution.

The paper presents dc fault current interruption performances of three different types of commercially available VIs . Owing to the differences in the contact system design; shape and size, contact material and composition as well as arc control mechanisms, the performances of the three VIs are completely different. Thus, the VIs can be optimized for dc current interruption. Moreover, re-ignitions and restrikes are very common which entails that the test methods need to consider adequate voltage stress across the insulation gap ( vacuum, SF6, air ) during the entire interruption process.
