If the diagram(Figs. i7, 38) is studied, it will be noted thatat the moment the arms of the commutatingdevices are in the position indicated, the hightension current is flowing from the trans-former, through the first arc, through the tirstarm to the first upper sector, through themilliampere meter to the positive side of the.
