A Method to Estimate the Necessary Twist Pitch in Multi-filamentary Superconductors
Lindau, Sandra Madeleine; Magnusson, Niklas; Taxt, Henning (Journal article; Peer reviewed, 2014)Twisting of multi-filamentary superconductors is an important step in the development of wires with AC losses at an acceptable level for AC applications. The necessary twist pitch depends on wire architecture, critical ... -
Ablation-assisted load current interruption in medium votage switchgear
Taxt, Henning (Doctoral theses at NTNU;2019:5, Doctoral thesis, 2019)The switching of loads and feeders in medium voltage (1-52 kV) networks is essential to the operation of distribution networks. Thus, medium voltage load-break switches are abundant in networks today and could become even ... -
AC Loss in MgB2 Superconductors: Calorimetric Loss Measurement
Taxt, Henning (Master thesis, 2012)Ever since the phenomenon of superconduction was discovered, and especially after the discovery of high-temperature superconductors (HTS) in the mid-80s, there has been high expectations to what could be achieved by this ... -
AC loss measurements multi-filamentary MgB2 wires with non-magnetic sheath material
Taxt, Henning; Magnusson, Niklas; Runde, Magne; Brisigotti, S (Journal article; Peer reviewed, 2012)The MgB2 superconductor is an attractive choice for many high-current DC applications, particularly for its low cost compared to e.g. YBCO, and the higher operating temperature than the low-temperature superconductors. To ... -
Apparatus for calorimetric measurements of losses in MgB2 superconductors exposed to alternating currents and external magnetic fields
Taxt, Henning; Magnusson, Niklas; Runde, Magne (Journal article; Peer reviewed, 2013)Inexpensive superconducting wires with low AC losses would open up for a large superconductor market in AC electrical power applications. One candidate for this market is the MgB2 conductor. In the development of an AC ... -
Coupling currents and hysteresis losses in MgB2superconductors
Magnusson, Niklas; Lindau, Sandra Madeleine; Taxt, Henning; Runde, Magne (Journal article; Peer reviewed, 2014)MgB2 multi-filamentary superconductors are widely considered for use in dc applications. To expand the possible application range to ac apparatuses, the development of a low ac loss wire is needed. This development involves ... -
Enhancing grid hosting capacity with coordinated non-firm connections in industrial energy communities
Bjarghov, Sigurd Nikolai; Foslie, Sverre Stefanussen; Askeland, Magnus; Rana, Rubi; Taxt, Henning (Peer reviewed; Journal article, 2024)A significant increase in grid connection requests from industrial customers has lead to long connection queues. Combined with long lead times on grid construction, the result is significant socioeconomic losses due to ... -
Experimental investigation on ablation-assisted current interruption - Experimental setup and preliminary results
Taxt, Henning; Niayesh, Kaveh; Jonsson, Erik; Runde, Magne (Chapter, 2016)This paper presents a flexible setup to investigate ablation-assisted interruption of load currents. The electrical test circuit is grid connected with a transformer secondary voltage from 6.9 kV to 24 kV. The applied ... -
Medium voltage load current interruption in presence of ablating polymer material
Taxt, Henning; Niayesh, Kaveh; Runde, Magne (Journal article; Peer reviewed, 2018)The expected abolishment of SF6-gas in medium voltage switchgear has prompted a search for replacements for the switch types that depend on SF6 to obtain the required capability, reliability, compactness and cost. Ablation ... -
