電流と同一となる。The discharge current flowing in the high voltage line flows to ground via the lightning arrester 1. At this time, a voltage drop corresponding to the discharge current occurs across the lightning arrester. Since the capacitor 2 is connected in parallel with the lightning arrester 1, it is charged up to the terminal voltage of the lightning arrester 1, and its polarity is also the same as the discharge current.

[Effects of the Invention] As described above, according to the present invention, since light emitting diodes with opposite polarity are connected in parallel to the lightning arrester, the number of discharges can be determined by controlling the polarity. Furthermore, due to the function of the capacitor connected in parallel to the lightning arrester, it has excellent effects such as being able to reliably detect the number of discharges even in short discharge phenomena such as lightning surges.
