Earth Fault

Detection System

Primary circuits are key to AGL installation. Their insulation level is a main concern for airports. It may not be a big issue from an electrical point of view, but it does impact operation as a low insulation can effect Airfield Ground Lighting brightness and it may also be a first sign of a more serious infrastructure issue.


EFD-GRP system will provide an accurate assessment of your primary circuit state and map its insulation level across the circuit.


This information is available 24/7, and will allow maintenance teams to monitor the evolution of the primary circuit status in time and depending on weather conditions, identifying hot spots and providing relevant information to plan and decide where and when to act saving hours of painful field research process.
