摘要:
Systems, methods, and computer-readable media are disclosed for impedance-based broken conductor detection in electric distribution systems. Upon the detection of a broken conductor, the affected overhead line will be de-energized before it hits the ground. An example method may include determining, during a first time period, a first impedance value measured by a first IED, and may further include determining, during a second time period that after the first time period, a second impedance value measured by the first IED. The method may further include determining a first ratio based on dividing a difference between the first impedance value and the second impedance value by the first impedance value, and may further include determining that the first ratio deviates from a threshold setpoint, and determining that a broken conductor condition occurs based on the first ratio deviating from the threshold setpoint.
