Abstract

Procédé et appareil de mesure et de calcul de tension de tenue d'entrefer, et dispositif informatique et support. Le procédé consiste : à acquérir, à l'aide d'un module d'interaction, le type et la polarité d'une tension de test appliquée dans un test haute tension ; en fonction du type et de la polarité de la tension de test, à déterminer une formule de conversion cible entre une tension de tenue et une distance d'entrefer ; à acquérir une distance d'espace réellement mesurée d'un entrefer à l'aide d'un module de mesure de distance ; à acquérir un paramètre d'environnement de test dans le test haute tension à l'aide d'un module de détection de paramètre d'environnement ; et en fonction de la distance d'espace réellement mesurée, du paramètre d'environnement de test et de la formule de conversion cible, à déterminer une tension de tenue correspondant à l'entrefer actuel.
