Abstract
A surge protector is for electrical connection between one or more power lines and one or more loads. The surge protector includes an input for electrical connection to the power line and an output for electrical connection to the load. A circuit electrically interconnects the output with the input for passing power therebetween. A metal oxide varistor protects the load from surges or transients on the power line. A voltage monitoring circuit detects an occurrence of an overvoltage event on the power line. A charged capacitor is shorted by the series combination of a fuse and a MOSFET switch to open the fuse and, thereby, permanently record the occurrence of the overvoltage event.
