Ground fault detection relay<\/strong><\/p>\n\n\n\n

For trackside installations, this ground fault detection relay measures the DC current from the frame to the ground.
Mainly installed in metro and tram DC substations, the relay is connected between the ground and the cubicle frame. In the event of an isolation failure, the fault current flows through the relay that picks it up. No auxiliary power is required.<\/p>\n\n\n\n

As an option, a permanent magnet gives the relay the ability to stay engaged even if the defect disappears, a top button allows manual rearmament. With this option, the relay can detect both AC and DC current.<\/p>\n\n\n\n
