SIST EN 61243-5:2002

Live working - Voltage detectors -- Part 5: Voltage detecting systems (VDS)

Is applicable to voltage detecting systems that are single-pole and are capacitively-coupled to live parts. They are used to detect the presence or absence of operating voltage on a.c. electrical systems for voltages from 1 kV to 52 kV, and for frequencies from 16 2/3 Hz to 60 Hz. This standard is also applicable to phase comparators designed for voltage detecting systems.

Arbeiten unter Spannung - Spannungsprüfer -- Teil 5: Spannungsprüfsysteme (VDS)

Travaux sous tension - Détecteurs de tension -- Partie 5: Systèmes détecteurs de tension (VDS)

Est applicable aux systèmes monopolaires détecteurs de tension en couplage capacitif avec des pièces sous tension et utilisés pour détecter la présence ou l'absence de la tension de service sur les réseaux électriques de tension alternative comprise entre 1 kV et 52 kV et à des fréquences comprises entre 16 2/3 Hz et 60 Hz. Cette norme s'applique également aux comparateurs de phase conçus pour s'adapter aux système détecteurs de tension.
