MEASUREMENT OF INTERFERENCE IN RAILWAY SUB-STATION FILTER INSTALLATIONS AND TRACK CIRCUITS CAUSED BY TRACTION VEHICLES WITH CHOPPERS

The measurements on the CSD railway test circuit were made for the following purpose: 1) to check the impedances of overhead line and sub-station at which the traction vehicle chopper works, 2) to identify the influence of the railway sub-station filter on the interference currents measured at the sub-station, and 3) to identify the degree of risk for the track circuit, when the working frequencies of the chopper and track circuit are identical.
