System and method for detecting a disturbance on a physical transmission line

A system for identifying at least one location of disturbance events on a physical transmission line, the system comprising:

• a computer system that comprises one or more processors programmed with computer program instructions that, when executed, cause the computer system to:
• obtain, from a first sensor among sensors on a physical transmission line, first sensor data, the first sensor data including first measured values of the disturbance event over a length of time;
• obtain, from a second sensor among the sensors on the physical transmission line, second sensor data, the second sensor data including second measured values of the disturbance event over the length of time;
• determine a first initial detection time of the first measured values and a second initial detection time of the second measured values;
• determine a time difference between the first initial detection time and the second initial detection time;
• approximate a first distance of the disturbance event from the first sensor based on the time difference and a known constant and a second distance of the disturbance event from the second sensor based on the time difference and the known constant;
• and
• identify a location of the disturbance event on the physical transmission line based on the determined first and second distances.

A method for identifying a location of a disturbance event on a physical transmission line, the method comprising:

• obtaining, from a sensing device located on the physical transmission line, sensing data, the sensing data including information regarding timestamp values of a light beam emitted by the sensing device and reflected back to the sensing device by a sensor located on the physical transmission line and information regarding a property of the light beam emitted by the sensing device and reflected back to the sensing device by the sensor;
• determining, based on the sensing data, (i) a roundtrip time of the light beam emitted by the sensing device and reflected back to the sensing device by the sensor and (ii) a change in the property of the light beam emitted by the sensing device and reflected back to the sensing device by the sensor;
• and
• identifying the location of the disturbance event on the physical transmission line based on (i) the roundtrip time of the light beam emitted by the sensing device and reflected back to the sensing device by the sensor and (ii) the change in the property of the light beam emitted by the sensing device and reflected back to the sensing device by the sensor.
