Abstract—Two units of an RZhFA-6500 reactor were put into operation into a current return circuit of the Uglerod traction substation of the West Siberian Railroad in series connection with RBFA-U-6500/3250 reactor as a part of a resonant-aperiodic L-shaped filter device. Before assembling the new type reactor, its inductances were measured with the ammeter–voltmeter method under alternating current. The phase-shift angle between current and voltage drop on the RZhFA-6500 reactor was not controlled. To check the operability of the new of type reactor and analyze its efficiency, a series of experiments in the regular and emergency operation modes of the dc traction power supply system were conducted. An experiment using a forced short circuit without cessation of the motion of electric vehicle over the section was performed. Oscillograms at the catenary feeder and the circuit of traction current return were synchronously recorded upon disconnection of a high-speed switch. A comparative analysis of harmonic composition of the voltage drops on the reactors of two types was carried out. The amplitude–frequency responses of traction current for different operation modes of the Uglerod traction substation were plotted. The method for calculation of the RZhFA-6500 reactor inductance based on recorded oscillograms in regular and emergency operation modes of the traction power supply system was developed and tested. A universal formula for inductance calculation taking into account the phase-shift angle between the current and the voltage drop on the reactor when measurements by the ammeter–voltmeter method was derived.
