Abstract	La protection des installations téléphoniques contre les surtensions générées par la foudre est une nécessité pour tout opérateur. France Télécom utilise donc différents dispositifs de protection parmi lesquels les parafoudres à gaz. Bien sûr, ľ étude de ces dispositifs ne peut se passer Ŀ expérimentations en grandeur réelle. Cependant une modélisation des parafoudres à gaz permettrait une meilleure spécification de leurs caractéristiques. Ľ objet de cette étude est ď avoir une bonne representation de la tension aux bornes du parafoudre ainsi qu’une bonne restitution de la réponse en courant. Nous proposons done une modélisation ď un éclateur à gaz, ainsi que son implantation sous Simulink (Matlab). Le nouveau modèle obtenu donne de bons résultats tant en tension qu’en courant. Il est totalement validé par comparaison avec des mesures obtenues lors ď une campagne de déclenchement artificiel de la foudre menée à St Privat ď Allierpar France Télécom.pots installation protection against overvoltages generated by the lightning is a necessity for every operator. France Télécom employ so various protective devices among which gas surge arresters. Naturally the study of these devices can not be done without experiments in real size. However a modelling of gas surge arresters would allow a better specification of their characteristics. The aim of this study is to have a good representation of the voltage in the borders of the gas surge arrester, and a good restoration of the current answer. We propose a modelisation of the surge arrester, as well as its implanting under Simulink (Matlab). New obtained model gives good results as in voltage as by current. He is totally confirmed compared with experimental measurements obtain during a campaign of trigerred lightning at S$^{t}$ Privat ď Allier by France Télécom.
