Sentinel™ Earth Fault Indicators
The Sentinel™ range of Earth Fault Indicators (EFI) are used for detecting earth faults in high voltage cable networks. Each unit has a core-balance sensor which is installed around the three phases of the cable being monitored.
The EFI will trip for a current in-balance due to an earth fault and provide visual indication. The EFI helps to quickly identity in which section of the cable network the earth fault is located.
