Device and method for displaying the lifecycle of a surge protection device
The present invention relates to a device and method for displaying the lifecycle of a surge protection device, and more particularly to a device and method for displaying the lifecycle of a surge protection device, which detects an increase in leakage current according to a deterioration in performance of the surge protection device in order to provide notice of a replacement time for the surge protection device. According to the present invention, it is possible to for a user to provide notice of a replacement time by displaying the lifecycle of a surge protection device (SPD) to the outside. Additionally, as another effect of the present invention, it is possible to confirm an amount of leakage current flowing into the ground of the SPD and whether the SPD is properly installed on a ground line by using a current and ground state detecting sensor.
