Abstract
A lightning surge detectorincludes a first terminal unitconnected to a ground-side terminal unit of a surge protective device, a second terminal unitconnected with a ground wire, a conducting coupling baradapted to couple the first terminal unitand the second terminal unit, a detection coilplaced in a vicinity of the conducting coupling barand adapted to detect a lightning surge current flowing through the conducting coupling bar, a waveform processing unit adapted to stretch a voltage waveform of the detected lightning surge current and thereby output a waveform-modified voltage, a computation control unit adapted to produce a calculation result of the lightning surge current from the waveform-modified voltage, and a display unitadapted to display the calculation result, wherein all the above components are unitized by being housed in a casing
