motor currents (last three lines) and the motor torque (first line) go to zero. It shows the motor voltages (line 3 and 4) changing from a rippled converter supply to the natural sinusoidal form of a generator. This is shown because the simulation does not consider the closing of the mill brake and the stop of mill and motor.
Siemens has always upheld the highest quality and safety standards in the manufacturing of medium voltage drives, but we are now taking safety a step further. Siemens Arc Defense Technology is the first in the industry to apply passive arcresistant features to medium voltage drives with integral transformers.
Siemens stated that the new drive systems will give a huge boost to the reliability and consequently also the throughput of the mills. The contract is valued in the doubledigit million range. The modernisation project includes two 8MW semiautogenous grinding (SAG) mills and two 1.7MW ball mills
