Abstract: PURPOSE:To specify a steel tower struck by lightning by providing a bypass to delay and guide an optical pulse to the width or above of the optical pulse at an optical fiber and providing an optical sensor to change the intensity of the leading pulse based on the information of respective measuring parts at the bypass. CONSTITUTION:A bypass 5 to delay and guide an optical pulse to the width or above of the optical pulse is provided and the bypass 5 is provided with an optical sensor 6 like a lightning detecting sensor to detect the presence and absence of the lightning at respective measuring parts with ON-OFF.
