との間での放電は起らない。しかし。As shown in FIG. 4, the operation display device using current recording paper connects a nonlinear resistor 2 containing charcoal-fired silicon between the lightning arrester l and the ground, and connects a coil 3 and current recording paper to this resistor 2. 4 are connected in parallel, and the leakage current of the lightning arrester 1 under normal conditions flows to the ground through the coil 3 whose impedance is lower than that of the resistor 2. At this time, since the coil 3 is set to 5Vc so that its impedance is sufficiently low in the AC frequency band, no high voltage is generated across the coil 3. For this reason, the current recording paper 4 and the discharge gap 5
No discharge occurs between the two. but.

る。When the lightning impulse current flows, the impedance of the coil 3 becomes higher than the impedance of the resistor 2, so this lightning impulse current flows through the resistor 2. As a result, a high voltage sufficient to cause discharge between the current recording paper 4 and the discharge gap 5 is generated at both ends of the resistor 2. As a result, the current recording paper 4 is burned out in proportion to the lightning impulse current due to the discharge action. Therefore, the magnitude of the lightning impulse current can be detected based on the degree of burnout.
