The lightning strike counter, OBVG-3M, is a device designed to detect lightning strikes on any external lightning protection system (including lightning rods, ESE systems, faraday cages, etc.).

OBVG-3M detects the electrical energy that is conducted to the ground through a conductor when a lightning strike occurs. The device registers each impact, increasing the counter by one unit for each strike. OBVG-3M should be installed in the down conductor that connects the lightning rod to the grounding system. It does not require any external power supply, as it utilizes the electric energy generated by the lightning itself.


A lightning strike counter is used to record the number of lightning strikes on various types of lightning eliminators and lightning rods.
