| titleOfInvention | Differential protection method and differential protection unit |
| abstract | The invention relates to a differential protection method for generating a fault signal (F). According to said method, current measured values (I1 (t), I2 (t)) are measured at least at two different measuring points (40, 50) on a component (80, 410) and are used to form differential current values (I-DIFF) and stabilising values (I-STAB), the fault signal being generated if a tripping range test establishes that a measured value pair, consisting of one of the differential current values and its associated stabilising value, lies within a predefined tripping range (320, 320'). According to the invention, the similarity of the current profiles is tested and a modified trigger range test is carried out depending on the degree of similarity (A), said trigger range test being modified in such a way that the trigger sensitivity for generating the fault signal is reduced as the similarity of the current profiles decreases. |
