On the possibility of calculating of the wires complex impedances and the repeat grounding connections resistances in the distribution network 380 V according to the accounting system data

The paper considers the issue of calculating of the wires complex impedances and resistances of the re-grounding connections in a three-phase distribution network. It is based on measurement data of the effective values of voltages and currents, as well as phase shifts between them, performed simult...
