We lost power again today. Lasted maybe three or four hours. Gnerator in the mean time. I up the voltage there to compensate for the loss to the house. It's 121 t both legs at the main. I know it's not correct cycle and such, but it works lamps and aquarium air pumps and filters. Wife is happy. But...it got me to thinkin' about the clean power we get at our houses. It's pretty far away from the source. I'm wondering how much loss is in those giant, tall and long transmission lines. Through all the step down transformers, too. What must they start out with to get us all what we need to be so....correct!!
