Comprehensive monitoring
Easily detect (locally and remotely) earth faults in medium-voltage cable networks up to 36 kV (± 10%), 50 Hz/60 Hz.
Why Earth fault indicator for cables - SICAM EFI?
Use SICAM EFI to detect earth faults in medium-voltage cable networks. It detects and indicates (locally and remotely) faults in radial or open ring cable networks of solidly or low-resistive grounded grids.
SICAM EFI continuously evaluates current values from external sensors. It promptly detects and signals an earth fault when a set threshold is exceeded, enabling faster service restoration and improving network availability.
Ensure continuous operation with a dual AC/DC power supply and battery, maintaining functionality after main power trips. Install easily using split core sensors, ideal for retrofitting to MV cables. Built-in restraints prevent false fault detections from inrush currents and auto reclosure operations, providing accurate, reliable indications.
Key benefits
Higher reliability
Detect and localize ground faults faster in radial and open-ring networks.
Faster service restoration
Rely on higher availability of the distribution network, less downtime and reduced revenue loss.
Easy configuration
Streamline setup using DIP switches.
