Based on the existing railway power telecontrol terminals resources, a fault location and isolation device is developed with the DSP of Type TMS320F2812 made by TI Company as the hardware platform. The communication con-nection protocol between the device and station FTU is via telecontrol 104 protocol,and Modbus TCP protocol is used as communication link between the device and I/O module. With the I/O module collecting the switching values on the outgoing circuit breakers at the two terminals the device can determines the direction of power supply and realize the fault location and isolation. The field test and operation results have verified stability and reliability of the device.
