Untersuchungen zur Beeinflussung des durch Störlichtbögen verursachten Überdrucks in elektrischen Anlagen
Fault arcs in electrical installations occur extremely seldom. However, they can not be avoided totally. Insulation failure, flashover, malfunction or maloperation by service personnel can lead to powerful fault arcs. As a result switchgear installations and even substation buildings may be …

Calculation of pressure rise in electrical installations due to internal arcs considering SF 6-air mixtures and arc energy absorbers
Internal arcs cause sudden temperature and thus pressure increase in electrical installations, which may endanger personnel, installation rooms or buildings as well as the security of power supply. Overpressure can be controlled by e.g. relief openings. The proof of internal arc withstand is …
