The arc detector system using power line carrier in railway

Recently, many technologies of the P.L.C (power line carrier) are introduced for an efficient communication. P.L.C communication sends information in the carrier signals by conduction over the power wire. An arc detector is proposed in this paper for the effective transmission. The power line carrier has an advantage in low cost because it uses existent power line. It can be easily applied anywhere that a power line socket is available. But the P.L.C. is very noisy, because many electronic devices in generate electronic noise in modulated signals. This problem should be considered carefully in the design of the arc detector system using P.L.C. The proposed system can be applied for monitoring the arc detector system and the arc locator system. The system is able to exchange the arc information to be T.C.M.S. (train control management system), bogies and even between a station and trains in railway.
