The recorder shall have a register that activates one count for every discharge where the peak current exceeds 1500A at the 8/20 micro second waveform and a maximum of 220 KA.

The lightning strike recorder shall be robust and easy to install. The counter shall operate from the energy of the lightning discharge and should not work on external or battery power to operate.

The lightning strike recorder shall be tested and certified as per IEC 60-1:1989 standard inline with the lightning arrester for a impulse current of more than 450 KA (8/20 micro second).

The lightning strike recorder shall be installed to the manufacturer€™s instructions in a readily accessible manner (always 2 mtrs above the ground) so that reading can be taken at regular intervals.
