Earth Leakage Detector
Detects earth leakage in AC/DC signalling circuits and alerts before a gear is lost.
Specification
Signalling circuits live and die by insulation. The ELD watches AC and DC circuits, raises an instant fault indication, and protects gears, infrastructure, and staff from progressive earth faults.
Capabilities
- AC and DC signalling circuits
- Instant fault indication
- Hut and location-box fitment
- Integrates with RDPMS
Applications
- IR signalling
- Metro signalling
- Yard interlocking
