SC25d Surge Counter

SETREON 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.

  • Minimum discharge 8/20µs current counted250A
  • Maximum discharge 8/20µs current counted100kA
  • Minimum impulse 10/350µs discharge current counted250A
  • Maximum impulse 10/350µs discharge current counted
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.
