Plugging or Reverse Current Braking In Plugging or Reverse Current Braking the armature terminals or the supply polarity of a separately excited or shunt motor when running are reversed. Therefore, in Plugging the supply voltage V and the induced voltage E b which is also called back EMF will act in the same direction.
The mill stand motor drives are the largest harmonic producing load on the plant's electrical system. Connected through stepdown transformers, these drives are 6pulse units generating predominantly a 5th harmonic current during operation. From the standpoint of the power supply, the rolling mill is divided into two sections. (See Fig. 1.)
