  • Patent number: 8730638
    Abstract: A lightning surge detector 1 includes a first terminal unit 3 connected to a ground-side terminal unit of a surge protective device, a second terminal unit 4 connected with a ground wire, a conducting coupling bar 5 adapted to couple the first terminal unit 1 and the second terminal unit 4, a detection coil 7 placed in a vicinity of the conducting coupling bar 5 and adapted to detect a lightning surge current flowing through the conducting coupling bar 5, 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 unit 40 adapted to display the calculation result, wherein all the above components are unitized by being housed in a casing 2.
    Type: Grant
