| Abstract: | The authors introduce a relay protection system of HV and large current of an electric railway trolly wire . In this system, the technology of fiber-optic and computer is used. So the transmission channel of detecting signal was is fiber-optic by which safty detecting and controlling HV quantity of electricity was realized. This relay protection has the quality with hight sped and accurate, house the core of the System of the data collection and controlling was single computer. |
