Components for low-voltage surge protection - Part 352: Selection and application principles for telecommunications and signalling network surge isolation transformers (SITs)

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. Keywords: surge isolation transformers (SITs), telecommunication transformer applications

Composants pour protection par parafoudres basse tension - Partie 352: Principes de choix et d'application pour les transformateurs d'isolement contre les surtensions (SIT) dans les réseaux de signalisation et de télécommunications

IEC 61643-352:2018 trait à l'application des transformateurs d'isolement contre les surtensions (SIT) utilisés dans des applications de transformateur de télécommunication dont les niveaux de signal atteignent 400 V de crête à crête. Ces transformateurs ont une tension assignée de tenue aux chocs élevée, avec ou sans blindage entre les enroulements d'entrée et de sortie. Les SIT sont des composants de protection contre les surtensions; ils sont utilisés pour atténuer la propagation de surtensions en mode commun. Le présent document traite du choix des SIT, de leurs principes d'application et des informations les concernant. Le présent document ne couvre pas les transformateurs de communication sur ligne d'alimentation. Mots clés: transformateurs d'isolement contre les surtensions (SIT), applications de transformateur de télécommunication

Sestavni deli za nizkonapetostne naprave za zaščito pred prenapetostnimi udari - 352. del: Izbira in načini uporabe izolacijskih transformatorjev (SIT) v telekomunikacijskih in signalnih omrežjih

V tem delu standarda IEC 61643 je obravnavana uporaba izolacijskih transformatorjev (SIT), ki se uporabljajo pri telekomunikacijskih transformatorjih z ravnmi signala do 400 V od vršne vrednosti do vršne vrednosti. Ti transformatorji imajo visoko nazivno udarno napetost z zaslonom med vhodnim in izhodnim navitjem ali brez njega. Izolacijski transformatorji (SIT) so komponente za zaščito pred prenapetostnimi udari in se uporabljajo za širjenje običajnega načina napetostnih udarov. V tem dokumentu so opisani izbor izolacijskih transformatorjev, načela uporabe in povezane informacije. Ta dokument ne obsega komunikacijskih transformatorjev elektroenergetskih vodov.
