A computer controlled system for high voltage studies / Slimane Rabahallah

Public ISBD Titre : A computer controlled system for high voltage studies Type de document : texte imprimé Auteurs : Slimane Rabahallah, Auteur ; B.H. Crichton, Directeur de thèse Editeur : Glasgow : [s.n.] Année de publication : 1986 Importance : 100 f. Présentation : ill. Format : 30 cm. Note générale : Master Thesis : Glasgow, University of Strathclyde : 1986 Bibliogr. f. 64 - 65 Langues : Anglais (eng) Mots-clés : Computer  controlled Studies High  voltage Index. décimale : Ms01886 Résumé : This thesis describes the design and operation of apparatus to repeatedly impulse test SF6-insulated gaps in order to examine the questions of basic performance of gas insulation. The distinctive feature of impulse voltage testing is that a rapidly rising voltage is applied to a system and results in either a breakdown or a withstand. When applied to gaseous insulants, impulse voltage measurements produce a wide statistical spread of results so that a large number of votlage applications is necessary to est-ablish reasonable confidence limits on the distribution. This can be time-consuming. Microcomputer technology allows a flexible answer to be given to this concept and such a system is described here with particular emphasis on low-cost solution.

A study of voltage-time characteristics in SF6 / Ahcene Lemzadmi

Public ISBD Titre : A study of voltage-time characteristics in SF6 Type de document : texte imprimé Auteurs : Ahcene Lemzadmi, Auteur ; B.H. Crichton, Directeur de thèse Editeur : Glasgow : [s.n.] Année de publication : 1986 Importance : 73 f. Présentation : ill. Format : 29 cm Note générale : Master Thesis : Electronics : Glasgow, University of Strathclyde : 1986 Bibliogr. f. 72 - 73 Langues : Anglais (eng) Mots-clés : Study Voltage-time Characteristics SF6 Index. décimale : Ms01686 Résumé : The gas discharge processes which are important to breakdown in SF6 are reviewed. The various proposals to model the volt-time characteristics of SF6 are described in detail, and the significance of the concepts of critical volume and catchment region is examined. Equipment is developed which allows the impulse testing of SF6 in order to experimentally investigate the model based on critical volume and catchment region. Apparatus to provide some degree of automatic control and recording of breakdown data is developed. A study of voltage-time characteristics in SF6 [texte imprimé] / Ahcene Lemzadmi, Auteur ; B.H.
