Instrument transformers - Three-phase inductive voltage transformers having Um up to 52 kV

This European Standard specifies the requirements and tests for new three-phase voltage transformers with Um up to 52 kV and frequencies from 15 Hz to 100 Hz, for use with electrical instruments or electrical protective devices. NOTE Single-phase voltage transformers connected in a three-phase bank are not covered in this document.

Messwandler - Dreiphasige Spannungswandler mit Um bis 52 kV

Diese Europäische Norm legt die Anforderungen und Prüfungen für neue dreiphasige Spannungswandler mit Um bis 52 kV und Frequenzen von 15 Hz bis 100 Hz zur Anwendung mit elektrischen Messgeräten oder elektrischen Schutzeinrichtungen fest. ANMERKUNG Einphasige Spannungswandler, die zu einem dreiphasigen System zusammengeschaltet sind, werden in dieser Norm nicht behandelt.

Transformateurs de mesure - Transformateurs inductifs de tension triphasés avec Um jusqu'à 52 kV

La présente Norme Européenne spécifie les exigences et les essais pour les transformateurs de tension triphasés neufs avec Um jusqu’à 52 kV et des fréquences comprises entre 15 Hz à 100 Hz, utilisés avec des appareils de mesure électriques ou des dispositifs électriques de protection. NOTE Les transformateurs de tension monophasés raccordés en un banc triphasé ne sont pas couverts dans ce document.
