STREAMER Lightning Strike Counter (LSC) is meant to count the number of lightning strikes based on the current flowing in a conductor . The 250A high sensitivity Surge Counter can be installed easily on the ground leads even on existing installations thanks to its split core transformer.

The counter display can be mounted top, bottom, back, or strapped up to 20 m from the measurement point. The device complies to the IEC 62561. Thanks to its IP67, housing, rugged materials and self power, the LSC is suitable for outdoor and hazardous atmospheres.

Key features

  • High measurement performance: from 250A minimum to 100kA detection
  • Outdoor device : IP67
  • No maintenance : self powered device, no battery
  • Easy cable installation : split core current transformer, 5 to 25mm cable diameter
  • Easy counter installation : bottom, top, back or strap mounting. Up to 20m cable length.
  • Durable device : glass window, stainless steel & HDPE plastic

Split core characteristics

Two versions of the split core exist, up to 16mm (as standard) or up to 20 mm (on request). The 16mm split core is suitable for ground lead with diameters from 5 to 26 mm. 250A minimum detection is achieved for diameters from 5 to 16mm. For diameters or airgaps above, the table below provides minimum detection current.
