The Lodestar PT2 fault indicator is designed for earth fault detection on medium‑voltage cable lines in 6–36 kV distribution networks. It includes robust earth fault sensor technology that ensures accurate fault detection. Its advanced control and signaling features allow quick response, significantly improving grid reliability and reducing outage time. The device is suitable for control panel or wall‑mounted installation.
Benefits:
- Earth fault detection – reliable phase‑to‑ground fault detection in cable networks.
- Dual fault indication – ultra‑bright LED and mechanical flag for clear local notification.
- Flexible power supply – 220 V DC, 110 V DC, or 220 V AC mains.
- Backup battery – standby lithium battery maintains LED indication during power loss.
- Adjustable setpoints – easy configuration via DIP-switches.
- Low battery indication – alerts when battery level is low.
- Three‑phase current sensors – sensors installed on all three phases.
