Lodestar CL0.5B was designed to work in isolated and compensated networks with extremely low levels of residual current. Lodestar CL0.5B has high accuracy of all types of faults detection.

In the event of a fault on an overhead line, the indicators flash using ultra-bright LEDs, with the flashing pattern corresponding to the specific fault type. To enable data transmission from the devices to the KOMORSAN data collection server or to the dispatcher’s SCADA system, the devices can be equipped with the Lodestar Smartbox or Lightbox data transmission unit.

Lodestar CL0.5B benefits:

Versatile installation – independent of conductor configuration and number of circuits.
Secure attachment – reliable clamp for firm mounting on the conductor.
Hot‑stick installation – easy mounting without de‑energizing the line.
Flexible SCADA integration – IEC 60870‑5‑104 via KOMORSAN software or direct DNP3 connection using a communication unit.
Directional fault detection – identifies fault current direction.
Any neutral grounding type – effective operation in any neutral grounding arrangement.
Versatile network compatibility – suitable for radial and looped networks with single or multiple feeds.
