FEATURES & BENEFITS
- Personnel safety assured by optical link between voltage detector and remote relay.
- Voltage detector itself is insulated even in case of capacitive divider breakdown and able to absorb fault energy.
- Remote indication of voltage presence/absence allow to avoid complicated and critical mechanical interlock.
- Largely used in earth switch and remote disconnector or for swapping energy feeders.
- Available both for MV or HV application.
- Typical application for automatic change of energy power for hospital or critical plants.
- Assure a fast and reliable indication locally and remote avoiding use of expensive voltage transformer
