Feature
- Higher availability of overhead line networks – reduced downtime.
- Quick fault detection – exact fault localization and information to maintenance teams.
- High degree of sensitivity, the measurement starts at @50A – reliable detection of high-impedance faults.
- Self-sustained sensors reduce the energy consumption of the device – enhancing the service life of the supply battery in the device (battery life: 10 years).
- Own security key and IPsec encryption for data exchange with SICAM FCG – highest protection against unauthorized access (intruders).
- Quick and easy device configuration with QR code on SICAM FSI and a web browser rather than DIP switches – high degree of user-friendly configurability.
- Maintenance-free design of the device – with the exception of a battery change after 10 years, the SICAM FSI is absolutely maintenance-free.
The large-size display of the initial commissioning year on the device enables operating personnel to see when the battery is due for changing while remaining on the floor. - Various flashing light frequencies depending on fault type – quick and precise fault diagnosis for the maintenance team.
