Abstract (in Japanese) (See Japanese page) 
(in English) We have quite a bit of experience for the broadcasting transmitting system, which are designing, management, maintenance, renewal, and avoidance for lightning damages in the transmitting equipment. At first, discussing the stray metal method on the device insulation and withstand high voltage. Especially, installation of the antenna-stay coil, and grounding on the electric power devices are basic techniques. Determination of the metal potential is very important for the circuit design and under-take construction of the surge current returning. Recently, the digital technique will be progressed many electric system conversely to the analogue technique. Basic analogue technique will be useful and required many field operation. This paper describes the method, which is avoidance from the stray metals portion on the transmitting system and improve the reliability management in digital era.
