ZGQ-12 Lightning Counter
General
ZGQ-12 lightning counter is used to record the number and the time of lightning strikes. The product applies the principle of current induction, uses single-chip technology to control a three-digit liquid crystal display, and records the lightning current with amplitude in the range of 0.5kA to 200kA.

Configuration
Working Principle
The inductance probe is installed on the wire (generally the ground wire) through which the lightning current passes. When the lightning current comes, the inductance probe collects the lightning current signal and converts it into the voltage signal. After signal processing, the voltage signal is sent to the display unit controlled by the single-chip microcomputer. One record of lightning current is generated. When the lightning current comes again, record the lightning current again until 999 times then reset.
