Lodestar CL25 BM


Lodestar CL25 BM is a fault indicator which is used in MV power distribution networks. A set of fault indicators Lodestar CL25 ВM is designed to localize the damaged area on overheadlines (OHL) of distribution power grids with a voltage of 6-35 kV, a network frequency of 50 Hz or60 Hz, with any type of neutral.

No need in additional pole-mounted RTU device anymore. Indicators communicate with one CL25 BM device via Bluetooth radio signal, then CL25 BM communicates by GSM with KOMORSAN and transmit data to any SCADA-System via IEC 60870-5-104.

Lodestar CL25 BM benefits:

  • 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.
  • Enhanced resistance to interference conditions in the air.
  • On-line monitoring is possible —devices include SMS-gateway.
  • Connection to any existing SCADA easily via IEC 60870-5-104 by using KOMORSAN software or by DNP3 directly to SCADA.
