Three-phase electric power is like a special type of power used in places that need a lot of energy, like factories, hospitals, and many others. It's made of three cables that carry electricity at the same time. It's like having three hoses that you turn on at the same time to get a lot more water flowing out compared to just one hose. Three-phase power can provide more power than regular single-phase electricity and is useful for large systems that need a lot of energy.
