Journal ArticleDOI
Investigation of the performance of CF 3 I Gas as a Possible Substitute for SF 6
TL;DR: In this article, the authors investigated the use of CF3I, which has lower Global Warming Potential (GWP), as a substitute gas for SF6 in gas insulated switchgear and gas circuit breakers.
Journal ArticleDOI
Area effect on electric breakdown of copper and stainless steel electrodes in vacuum
TL;DR: In this paper, the breakdown field strength of gaps made with pure copper and stainless steel was investigated and the results showed that the area of effect of E/sub b/ is represented by the area effect of beta /sub l/ and that the vacuum breakdown may be initiated by field emission.
Journal ArticleDOI
Interruption capability of CF/sub 3/I Gas as a substitution candidate for SF/sub 6/ gas
TL;DR: In this paper, the authors measured the arc time constant and arc power loss coefficient using Mayr's equation and evaluated the short line fault (SLF) interruption capability by measuring the di/dt-dv/dt characteristic.
Journal ArticleDOI
Study of Superconducting Fault Current Limiter Using Vacuum Interrupter Driven by Electromagnetic Repulsion Force for Commutating Switch
TL;DR: In this paper, the authors constructed and tested a model superconducting fault current limiter (SFCL), where the superconductor and the vacuum interrupter as the commutation switch were connected in parallel using a bypass coil.
Journal ArticleDOI
History of vacuum circuit breakers and recent developments in Japan
TL;DR: Vacuum circuit breakers (VCBs) have been developed and widely applied in Japan to meet the requirements of increasing energy consumption and also in national security of various areas.
