SC25d Surge Counter
Description
Streamer Electric Lightning Strike Counter is meant to count the number of lightning strikes based on the current flowing in a conductor.
Surge Counter can be installed easily on the ground leads even on existing installations thanks to its split core transformer.
The DIN frame counter shall be back mounted on a DIN rail, up to 20m from the measurement point.
The CT and the connecting cables exists in 2 versions Indoor and outdoor IP68 rugged.
High sensitivity universal counter:
• Monitoring of lightning protection equipment: lightning rod, surge arrester, SPD, ground lead, ground rod;
• high measurement performance: from 250A minimum to 100kA detection;
• counts lighting impulse separated by more than 50ms;
• indoor device: IP42;
• outdoor and rugged version of split core current transformer IP68;
• no maintenance: self powered device, no battery;
• easy cable installation: 5 to 25mm cable diameter;
• up to 20m cable length.
Key features
• Easy installation: any place on an earthing wire
• Performance monitoring simplified: indication unit can be even at eyes level
• High sensitivity: 250 A minimum sensitive current
Lightning events are composed of up to 10 strokes (impulses) and 3 in average. The interval between lightning stroke is in average 50 ms, the SC25d is able to count every stroke/impulse during a lightning event down to 250 A so you won't miss a thing.
