Following the River

Bridgeport, WA

Chief Joseph Dam on the Columbia River. Twenty seven
large pipes called "penstocks" carry water down to the
hydropower turbines that generate electricity.

Great link charlie! The reason I ask is I worked at the Wolf Creek Nuclear power plant when it was being built and on breaks I would walk around observe and soak in as much as I could. I remember being in the generator room and seeing the generators but I swear I remember seeing a label on one of the generators that said 120/208 3 phase which I would think would be highly unlikely but I remember seeing it. Maybe it was a auxiliary generator for onsite power I just don't know. I also remember working inside massive circuit breakers where several people could stand inside it. The kind where you had to have a motor to close the switch. I also recall one of the GE engineers we worked with saying it was 13 KV switch, I don't remember the amperage. Paul

Power is generated at 13.8 KV, then stepped up to two transmission level voltages: 230KV and 540KV. Here is a link to some reading material about Chief Joseph Dam:

Charlie do you know what the output voltage directly from the generators is before it gets stepped up to its transmission voltage? Paul
