Ever wondered how the tiny bits of dirt on electrical contacts can make a big difference in how efficiently we use energy? Let's dive into a fascinating study that used mathematical modeling and simulations to figure this out. These electrical contacts carry super high currents, like 3000 A, in many electrical devices. When these contacts are exposed to nasty weather, they can get all worn out. This makes them less effective, and that's a problem in power transmission systems. So, scientists looked at the temperature changes in these contacts when they were clean and when they were dirty. Guess what? A clean contact stayed 80 °C cooler than a dirty one. This means clean contacts help in better energy transmission. The study also gave power grid operators some cool tips on maintaining these devices when temperatures go up.
