Instalimet e shenjave dhe tubave të ndriçimit gazshkarkues që punojnë nga një tension në dalje pa ngarkesë dhe që vlerësohet se e kalon 1kV por nuk kalon 10 kV - Pjesa 2: Kërkesa për pajisjet mbrojtëse ndaj qarqeve të hapura dhe difekteve të izolimit

Signs and luminous-discharge-tube installations operating from a no-load rated output voltage exceeding 1 kV but not exceeding 10 kV - Part 2: Requirements for earth-leakage and open-circuit protective devices

Scope

This European Standard specifies requirements for earth-leakage and open-circuit protective devices designed to protect circuits for neon tubes operating from transformers conforming to EN 61050 at voltages exceeding 1 000 V but not exceeding 10 000 V. NOTE 1 Requirements for the installation of earth-leakage and open-circuit protective devices are given in EN 50107-1. NOTE 2 Requirements for earth-leakage and open-circuit protective devices used with inverters and converters are specified in EN 61347-2-10.
