A MODEL FOR LOW VOLTAGE BREAKDOWN OF THE INSULATORS OF THE REACTOR’S WIRING SYSTEM

للكاتب E.A. EISAWY Operational Safety Dept., National Center for Nuclear Safety ABSTRACT The important deterioration phenomenon for the insulators is electrical damage to its surface in the presence of high humidity and contamination, possibly aggravated by high radiation doses. A model has been developed which predicts, the probability of an electrical breakdown for different temperatures and protective measures. In this …

THE INFLUENCE OF SURFACE RESISTIVITY ON ELECTRICAL INSULATORS OF THE REACTOR

للكاتب E. A. Eisawy Operational Safety Dept., National Center for nuclear safety ABSTRACT The paper presents an important simplification by introducing the surface resistivity to classify and estimate the deterioration breakdown process. The results show that the breakdown voltage increases with increasing surface resistivity of the insulator. Several test methods have been developed to examine the performance of insulators in …
