A surge current measuring device that is easy to use and offers excellent cost performance.

In the event of a failure caused by lightning strikes, the operation check of the surge checker that detects lightning within the range allows for the rapid identification of failure points caused by lightning. It can be installed and replaced simply by attaching it while the line is live, without cutting the ground wire or causing a power outage, making it easy for anyone to use with a straightforward method. Since it does not require a battery for operation, maintenance of the machine itself is unnecessary. It can be used as a criterion for verifying surge currents and determining the priority of inspections needed for equipment. The Surge Checker A is a reusable physical operation indicator that operates with an 8/20μs waveform. It is a product that offers a reasonable price and high reliability.
