eng	Traction converting substation from viewpoint of Freding interlocking plant at Czech Railways	The paper presents analyses current and voltage harmonic in traction converting substation 3 kV. It researches their rise and influence to three-phase cable line 6 kV, 50 Hz that is used for feeding interlocking plant. Processing of this task is arisen from requirement practice for line Pěčky - Poříčany - Rostoklaty where happened to adverse ratio in particular transmission line of feeding system. It is meant especially about backward influence traction substation rectifier Pečky to three-phase cable line 6 kV, 50 Hz. At the determinate length of the cable line, when resonance frequency of circuit transformer 22 kV/ 6kV and the cable line 6 kV, 50 Hz is approached frequency 550 Hz and 650 Hz (i.e. 11 and 13 harmonic) are happened to so-called ?annulations input reactance of this circuit?.
