Title The effect of fault currents with d.c. components on the trip characteristics of differential circuit breakers
Original title Die Beeinflussung des Ausl÷severhaltens von Fehlerstromschutzschaltern durch Fehlerstr÷me mit Gleichstromkomponenten [in German]
Bibliographic information Dec 1981, Vol.98, No.12, p.504-510. Illus. 13 ref.
Abstract The use of semiconductors in electronic asemblies is the cause of fault currents with d.c. components; these d.c. components are caused, in particular, by the phase adjustment. The effects on the human body of direct current and of alternating current with d.c. components are studied, and conclusions are drawn as to the trip characteristics of differential circuit breakers for protection against fault current with d.c. components. Review of the principles of differential circuit breaker protection agaisnt direct and indirect contact in earthed and earthed-to-neutral nerworks.
