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 : up to 3 split cores current transformers, 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

Current transformers device
The 3 current transformers SC250 is in all point similar to the 1 current transformer SC250 in terms of detection levels, electrical characteristics, withstand, performance and dimensions |
|
SADC20z mounted with SC250 with 3 current transformers |
The device has been designed to monitor 3 earthing point simultaneously, that could include for example 3 x LLPD, as the LLPD have not be design to have specific groundings OR as the grounding path might not be unique. The counter will totalize the surges on one unique counter, therefore it will not be possible to distinguish which location (current transformer) the surge originated from. The usage of a 3 current transformers is justified to reduce time and cost of installation and ensure proper detection |
