The present disclosure pertains to detection of a broken conductor in an electric power system. In one embodiment, a broken conductor detector may be configured to be mounted to an electrical conductor and may comprise a communication subsystem configured to transmit a signal configured to indicate that the conductor is broken. A sensor may determine an operating vector. A processing subsystem may be configured to receive the operating vector from the sensor and to identify when the operating vector is outside of a range defined by a rest vector and a threshold value. In certain embodiments, the threshold may comprise a three-dimensional sphere. The processing subsystem may determine that the conductor is broken based on the operating vector remaining outside of the range for a period of time determined by the timer subsystem. A signal may be transmitted by the communication subsystem to indicate that the conductor is broken.
