Lodestar CL0.5В Master


Lodestar CL0.5B Master model is a simple solution for fault detection. The registering of faults is based on special intelligent algorithm, that makes possible to detect PtG fault and its direction from 0.5A.

No need in additional pole-mounted RTU device anymore. Indicators communicate with one CL0.5B Master device via Bluetooth radio signal, then CL0.5B Master communicates by GSM with KOMORSAN and transmit data to any SCADA-System via IEC 60870-5-104.

Lodestar CL0.5B Master benefits:

  • Minimum fault sensing 0.5 A;
  • Detection of direction of all types of faults;
  • Brightest Light 360° Visibility - 3 ultra bright wide-angle LEDs provide overlapping fields of light;
  • Simple installation - using a single hot stick;
  • Dynamically changing sensitivity based on a load current;
  • Auto-Detect Network Frequency — intellectual algorithms allow it to work in networks with frequency of 50 or 60Hz without reconfiguration;
  • Connection to any existing SCADA easily via IEC 60870-5-104 by using KOMORSAN software.
