Operation analysis of leakage protection including auxiliary current source operating as series ohmmeter systems.
No. 2(530) 2017, pp. 43-50
This paper outlines issues related to the features of the leakage protections, especially the resistance of central leakage protections provided with the auxiliary current source to network interferences. It reveals susceptibility of the central leakage protections to this type of interferences (especially in the case of usage current sources of small rated currents).
