Abstract (en)
[origin: WO2009092398A1] The invention relates to a method for determining a fault location value (F) indicating a fault location of a short circuit (17) that occurred in an electric energy supply network, wherein after the start of the short circuit, current measurement values and voltage measurement values of a conductor affected by the short circuit are detected. From at least several of the detected current measurement values and from the voltage measurement values detected at the same time, a result impedance value is calculated. From the result impedance value, the fault location value (F) is determined. The invention further relates to a corresponding fault locator (16).
