ACT (RS) ABB Loco (English) (13. HARMONIC FILTTER)
January 10, 2021

Harmonic Filter Line harmonic filter is connected with primary winding of main transformer which consist of resistances and capacitor. This harmonic filter reduces/suppressed the high frequency harmonics to avoid disturbances in signaling. If the harmonic filter get bypassed by the system, the speed of the loco / train will be automatically
