13. 7 rectifier transformers each
Rectification is the process of obtaining an E.M.F. of
definite mean value from one of zero mean value.
In our system we have used silicon rectifier/high
power silicon diodes for rectification.

18. Power is stepped down from 132KV to 11.5KV by the four power
transformers having the following ratings.
T-1: 75 MVA
T-2 : 75 MVA
T-3 : 75 MVA
T-4 : 75 MVA
Above transformers supply power to Potline #1, 2 & 3, Auxiliaries to
Smelter Plant, Fabrication plant, Colony etc.
Capacitor are installed on the 11.5KV side of transformers T1 & T2 to
improve power factor
