Feature

The lightning strike counter can record the number of lightning strikes and instantaneous overvoltages of various lightning protection devices. The counting frequency is two digits, with a maximum of 99 times. The lightning strike counter is installed on the grounding wire of the surge protector, with an operating current of ± 3KA (8/20 μ s) and a maximum counting current of 150KA (8/20 μ s).
The lightning strike counter is equipped with a current transformer. When installing and using, insert the current transformer into the PE line of the surge protector, and lead the two wires of the secondary coil of the transformer into the 5 and 6 terminals of the lightning current counter, firmly connect them, and press the display switch to display the recorded number of times.
The lightning current counter has 6 terminals, with terminals 1 and 2 connected to N and L lines to provide working voltage for the counter. 3. Four terminals can be short circuited to reset the counter to zero. 5. Two terminals are connected to the two leads of the current transformer coil.
