适用范围：protection in telecommunications, signalling and low-voltage power distribution networks withnominal system voltages up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c. They are defined as agap, or several gaps with two or three metal electrodes hermetically sealed so that gasmixture and pressure are under control. They are designed to protect apparatus or personnel,or both, from high transient voltages. This standard provides information about thecharacteristics and circuit applications of GDTs having two or three electrodes. This standarddoes not specify requirements applicable to complete surge protective devices, nor does itspecify total requirements for GDTs employed within electronic devices, where precisecoordination between GDT performance and surge protective device withstand capability ishighly critical.
