One of my high-school science-fair projects was a fractal high voltage insulator. The idea was that since high voltage follows the surface of an object, why not give it a lot of surface to run out of energy on? I failed of course - the ceramic was too hard to work (I dulled so many saw blades). And I didn't have an oven to bake it at the required temperature profile, nor a high-voltage lab to test my designs. But a cool idea anyway.
- namibj 8y agoYou want a shere/distance/minimize maximum curvature.
- chiph 8y agoAn unanswered question was whether the voltage would just jump across the edges of the fractal or follow the surface of the ceramic. Which would likely vary with humidity. I'm sure that General Electric & Siemens test in all kinds of weather conditions - another thing I couldn't do. ;)
