Annotation of standard text IEC 61643-352-ed.1.0 :
IEC 61643-352:2018 covers the application of surge isolation transformers (SITs) that are used in telecommunication transformer applications with signal levels up to 400 V peak to peak. These transformers have a high rated impulse voltage with or without screen between the input and output windings. SITs are components for surge protection and are used to mitigate the onward propagation of common-mode voltage surges. This document describes SITs selection, application principles and related information. This document does not cover power line communication transformers. IEC 61643-352:2018 trait a lapplication des transformateurs disolement contre les surtensions (SIT) utilises dans des applications de transformateur de telecommunication dont les niveaux de signal atteignent 400 V de crete a crete. Ces transformateurs ont une tension assignee de tenue aux chocs elevee, avec ou sans blindage entre les enroulements dentree et de sortie. Les SIT sont des composants de protection contre les surtensions; ils sont utilises pour attenuer la propagation de surtensions en mode commun. Le present document traite du choix des SIT, de leurs principes dapplication et des informations les concernant. Le present document ne couvre pas les transformateurs de communication sur ligne dalimentation. Mots cles: transformateurs disolement contre les surtensions (SIT), applications de transformateur de telecommunication
