05-01-2021

GFC CONTROL CIRCUIT     To move the loco, field of Traction Alternator is to be excited by exciter generator. This work is done with the help of GFC contactor. It is electro magnetic contactor. To pickup this contactor GFC coil circuit is designed. This circuit starts from wire no. 13. When both control stand GFCO kept in close and MH closed (MH 1 – 8), the supply of wire no. 13 goes to wire no. 6 via wire no. 30E, 30C, and 30CC. Supply of wire no. 6 goes to GFC coil through following normally close interlocks BKT (M)    NCI     6-6A ECS(R)       NCI     6A-6 GFOLR      NCI     6B-6C   GR1           NCI     6C-6D BKT (M)
