摘要（英）：

The invention discloses a transmission line double-terminal fault ranging system comprising a high-frequency data acquisition module, a power-frequency data acquisition module, a control logic circuit module, an A/D conversion module, and a computer device. The high-frequency data acquisition module is used for acquiring high-frequency data. The low-frequency data acquisition module is used for acquiring low-frequency data. Data acquisition of the high-frequency data acquisition module and the power-frequency data acquisition module is synchronously controlled by the control logic circuit module, and therefore, simultaneity of acquired data is ensured. The A/D conversion module is used for converting the high-frequency data acquired by the high-frequency data acquisition module and converting the low-frequency data acquired by the low-frequency data acquisition module. The computer device is used for carrying out fault ranging according to the data after conversion. A transmission line double-terminal fault ranging system is realized without a GPS.
