(Main)Components for low-voltage surge protective devices - Part 311: Specification for gas discharge tubes (GDT)
Components for low-voltage surge protective devices - Part 311: Specification for gas discharge tubes (GDT)
Gas discharge tubes (GDTs) are used for applications up to 1 000 V a.c. or 1 500 V d.c. in communication or signalling circuits. They are defined as a gap, or series of gaps, in an enclosed discharge medium other than air. They are designed to protect apparatus or personnel, or both, from high transient voltages. This standard does not specify requirements applicable to complete surge protective devices, nor does it specify total requirements for GDTs employed within electronic devices, where precise coordination between GDT performance and surge protective device withstand capability is highly critical.

Composants pour parafoudres basse tension - Partie 311: Spécifications pour les tubes à décharge dans un gaz (TDG)
Les tubes à décharge dans un gaz (TDG) sont utilisés dans des circuits de communication et de signalisation sous des tensions jusqu'à 1 000 V en courant alternatif ou 1 500 V en courant continu. Ils sont définis comme des éclateurs ou série d'éclateurs dans un espace fermé avec gaz de décharge autre que l'air. Ils sont conçus pour protéger des équipements ou des personnes, ou les deux, contre des surtensions transitoires élevées. La présente norme ne traite pas de prescriptions des parafoudres complets, ni des spécifications complètes des TDG utilisés dans les dispositifs électroniques où une coordination précise entre les performances des TDG et la résistance des parafoudres aux surtensions est primordiale.
