    Abstract: This paper designed a kind of function indication circuit used for gap-stack type of lightning protection device. This circuit used the principle of comparing the gap breakdown voltage with the indication circuit operation voltage. Combined with the fuses and the luminous tube devices, this system indicated the functions of lightning protection device via the electronic mode and the mechanical mode. On the basis of the relevant standard, the results of surge impact coordinated with the lightning protection device were tested. The experimental verification shows that this indication circuit can effectively indicates the functional status of gap-stack lightning protection device to make the terminal client conveniently and clearly affirm the performance conditions of the lightning protection device.

    Key words: lightning protection device; gap-stack; function indication circuit
