SPD action times (Surge counting) monitoring:
It is composed of built-in current sensing device, signal processing circuit and electromagnetic counter. The current sensing device is
connected with the surge protection device into the ground line. The induced current signal is recorded by limiting the amplitude,
rectifying and filtering the electromagnetic counter to record the surge strike times. s.
