LIGHTNING PROTECTION SYSTEMS

LST-87 Lightning Strike Counter

Share this

The lightning counter is an electromechanical device whose function is to count the number of times lightning strikes on a lightning rod.

The counting device is protected by a metal shielding, whose main function is to protect it against inclement weather.

"NOW IT'S POSSIBLE TO MEASURE THE WORKLOAD OF A LIGHTNING ROD"

The metal shielding protects it from water, dust, UV rays, etc. It also protects you from electromagnetic interference by complying with Michael Faraday's principle of electromagnetic induction or commonly called "Faraday's Law."

It has a display where you can see the digits that indicate the number of impacts computed, and a conduit through which the connection to the grounding of the collector system must be inserted. 


Lightning Strike Counter Installation

Serial Installation

From the lightning rod installation column or mast, a sheathed-copper cable of up to a maximum of 1.4in² is made (preferably bare, 2in² section) at a height of approximately 3.3 feet from the ground.

This branch must be inserted through the metal cabinet's through-hole and connected directly to the grounding system, either to the javelin's neck or to the installation's grounding system. 

How Does the Lightning Strike Counter Work?

The operating principle of the lightning strike counter is to use the discharge-induced current as follows:

When a lightning discharge occurs, the current circulates from the point of impact (lightning conductor) to the ground, circulating through the connecting cable and diverting a minimal portion of the current to circulate through the lightning strike counter.

The lightning strike counter is able to use the electromagnetic field that generates the passage of this current through the connection cable, and this signal is applied to an electronic circuit that controls the meter to increase its count by 1 unit.

It is likely that, in what at first glance seems like a single lightning "strike" event, several discharges will be caused due to the lightning wavefront that is extremely steep. 

The lightning strike counter technology added to the efficiency of its components, gives us the ability to count several sudden discharges one after another without having to wait for a discharge of the residual voltage that remains in its components. 

Its function is to inform the amount of lightning impacts received in the installation so that the insulation of the electrical installation, the state of the overvoltage protections, the sensor systems, etc. can be checked later. 

The operating principle of the lightning strike counter is to use the discharge induced current as follows:
