Determination of the danger of the occurrence of stray currents in electrified DC urban transport

Electrified urban transport occupies an important part of the life of every modern society. This paper describes some of the negative processes caused by electrified rail urban transport. Paper deals with overview of the measurement types related to controlling the leakage current from the rail network in ground electric transport (tram). Results of measurements carried out at the “Yunak” traction substation are presented.
