Instrument transformers - Part 5: Capacitor voltage transformers

This part of EN 60044 applies to new single-phase capacitor voltage transformers connected between line and ground for system voltages Um 72,5 kV at power frequencies from 15 Hz to 100 Hz. They are intended to supply a low voltage for measurement, control and protective functions. The capacitor voltage transformer can be equipped with or without carrier-frequency accessories for power line carrier-frequency (PLC) application at carrier frequencies from 30 kHz to 500 kHz.

Transformateurs de mesure - Partie 5: Transformateurs condensateurs de tension

La présente partie de la EN 60044 s'applique aux transformateurs condensateurs de tension monophasés neufs connectés entre la ligne et la terre pour des tensions de réseau Um 72,5 kV aux fréquences industrielles comprises entre 15 Hz et 100 Hz. Ils sont destinés à fournir une basse tension pour les fonctions mesure, commande et protection. Le transformateur condensateur de tension peut être équipé avec ou sans accessoires de couplage pour courant porteur sur ligne (CPL) aux fréquences porteuses de 30 kHz à 500 kHz.
