Schematic Definition and 92 Threads

A power generation plant converts chemical (or nuclear) energy into electrical energy. This energy is then sent out via conductive transmission line. What would be a simple schematic for this process? That is, if we liken it to a battery, then the positive pole would be the high voltage...
