LSC-7D

The counter displays the number of lightning strikes that have hit a system. The counter is for use on tower legs or cable conductors. It connects to two points on the conductor, spaced at least 8 feet apart, using 14 AWG (25 mm2) insulated wire. Features include weatherproof NEMA 4X & IP65 enclosure, internal protection, and seven digit readout. This device easily mounts to any flat surface. The Light ning Strike Counter LSC-7D is acceptable for outdoor use.

The LSC-7D connections should be electrically attached to the tower or the lightning protection system (LPS) down conductor using 14 AWG (2.5mm2) insulated wire and be separated by approximately 8.0 ft (2.4m). The inductive voltage drop due to a lightning strike will actuate the counter. A log should be kept to record the date and counter reading. To test your counter, voltage may be momentarily applied using a 9V battery in either polarity to actuate the circuit. The LSC-7D requires a 0.5 μH inductance shunt (approximately 8.0 ft conductor length) to count nature’s smallest lightning strike (3 kA). This inductance can be in the form of a wire length, tower, or pipe segment. To calculate, use the following approximations:
