Abstract
Interference currents in railway trackside signaling apparatus are monitored by first and second transducers adapted to measure the traction current and frequency, respectively, of power electronics in traction systems of railway vehicles. An instantaneous interference current value is determined, based on data output from the first transducer. Data output from the second transducer is used to determine digital filter outputs for the trackside signaling frequencies for the interference current value. The determined interference current value and digital filter output values are recorded on a data storage medium and displayed on a display unit.
