METHOD AND DEVICE FOR IDENTIFYING THE LOCATION OF A FAULT IN AN ELECTRICAL POWER DISTRIBUTION NETWORK

Method and device for determining a fault location in an electric power distribution network with an infeed and lines in the form of a main strand and a multiplicity of branches of the main strand. First and second measured values are acquired at a first and second measurement point of the power distribution network, and a fault location is determined based on the first and the second measured values. Arrival of respective traveling waves are identified based on the first and the second measured values, and the times of the respective arrival of the traveling wave are stored. A first fault location value is generated using the respective times of both measurement points and a second fault location value is generated using the times of only the first measurement point. The fault location is determined based on the first fault location value and the second fault location value.
