| titleOfInvention | Process and measuring the loop resistance of a distribution network |
| abstract | The invention relates to a method for determining the loop resistance of a power supply network with a neutral conductor (called N), a phase or an outer conductor (called L1), an earth or a protective conductor (called PE), and a fault current switch (called FI) on the basis of the difference quotient where U1 is the measured unloaded mains voltage, I1 is the zero-sequence current without load, U2 is the measured loaded mains voltage and I2 is the calculated load current. According to one aspect of the invention, the following steps are provided: loading a loop L1-N and determining the resistance R L1 according to equation (1), loading a loop N-PE with a measuring current I M under a measuring voltage U M that is small enough, to avoid triggering the residual current switch and determining the resistance R PE according to the following equation (2): and determining the loop resistance as R L1 + R PE . |
