摘要（英）：

The invention provides failure detecting equipment of a power communication transmission channel, a failure detecting system and a method. The equipment is characterized by comprising a transmitting end synchronous digital transmission device, an interference signal generating device and a receiving end synchronous digital transmission device, wherein the transmitting end synchronous digital transmission device is used for receiving state data transmitted by transmitting end protecting equipment and transmitting the state data into an optical fiber for transmission; the interference signal generating device is used for adding an interference signal into the state data; and the receiving end synchronous digital transmission device is used for receiving the state data transmitted from the optical fiber and transmitting the state data to receiving end protecting equipment for carrying out detecting processing. The embodiment of the invention adds simulating interference into the inward transmitted data of the transmission channel and can detect the performance of a relay protecting device in real time and execute alarm operation in time.
