Answer / rvg.msceb

These are main types of sub-stations.
1.at generating stations: step up voltage to higher level
2.at intermediate stations: step down voltage to lower level
say 400Kv to 11kv, and power factor improvement may be also
doing within these sub station

3.At load center: Where voltage is getting down to 400volts,
and this is near to be load center
