Abstract

The paper describes the procedures implemented in the design and testing of the newly built traction substation, which is foreseen for the power supply of part of the electrical tracks in the area of Zagreb. The power capacity of the new traction transformer substation was determined according to the load flow calculation that was carried out for the period of maximal traffic time-table. During the period of test operation a number of measurements were conducted in order to testify technical performances of the substation, as well as to verify its impacts on the environment. Measurements of the power quality in the utility power network, which supplies the traction system, were conducted. Also, measurements of electrical and magnetic fields inside the traction substation and in its vicinity were undertaken.
