Ageing of Technical Air and Technical Air with 7.5% C5-Fluoroketone by Free-Burning Arcs
(Journal article; Peer reviewed, 2023)This paper reports on the effect of ageing by free-burning arcs in 7.5% C5-fluoroketone (C5-FK) with 92.5% technical air in comparison to that in technical air (80% N2, 20% O2) at 1.3bar absolute pressure. The gases are ... -
Air Flow Measurements During Medium-Voltage Load Current Interruptions
(Journal article; Peer reviewed, 2015)Air has been considered a good alternative to SF6 as arc quenching medium for load break switchgear at medium voltage ratings. In this work, the air flow characteristics and influence from the electric arc have been studied ... -
Characterization of Ultrahigh Pressure Nitrogen Arc Using Black Box Arc Model
(Journal article; Peer reviewed, 2023)In this paper, the effect of filling pressure on the black box arc parameters of nitrogen arc is reported using Mayr arc model. The arc current is approximately 130 A at 190 Hz. The filling pressure is varied at absolute ... -
Impact of Ablation Based Self Blast Nozzles on Load Break Switch Current Interruption Performance
(Journal article; Peer reviewed, 2023)In this contribution, SF6 free ablation assisted medium voltage load break switchgear, has been investigated. In these switches, gases generated by the arc polymer interactions are trapped in expansion chambers and are ... -
Nozzle Wear and Pressure Rise in Heating Volume of Self-blast Type Ultra-high Pressure Nitrogen Arc
(Journal article; Peer reviewed, 2019)This paper reports on experiments with ultra-high pressure nitrogen arcs in a self-blast type switch design. The effect of filling pressure on nozzle mass loss and pressure-rise in the heating volume is investigated. An ... -
