Abstract

PURPOSE: To accomplish a step advancing command at the state of no auxiliary equipment is started on the same condition as that during the power running by feeding current to coils wound in specified turns around a nocurrent detection current transformer.
CONSTITUTION: Coils C1 and C2 are wound in specified turns around nocurrent detection transformers separately inserted between an odd tapping and an even tapping of a tap changer and a main magnetic amplifier. Deficiency detection indicator circuit FDC inputs a tap advancing command, a tap returning command, a send command, phase commands for the odd tapping and the even tapping and odd and even tapping commands at the state of no ausciliary equipment is started to supply current to the coils C1 and C2 while indication lamps LP1WLP7 are lighted. Thus, a step advancing command is performed at the state of no auxiliary equipment is started on the same condition as that during the power running of a loccomotive.
