ACT (RS) ABB Loco (English) (13. HARMONIC FILTTER)

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 restricted up to max 40 KMPH by CE.
