Why don't three-phase electricity use zero line?
When three-phase electricity is connected in a triangle, there are only three-phase lines and no zero line, so there are only three-line transmission; When star connection is adopted, although there are zero lines and three-phase lines, the three-phase current is basically balanced, and there is no current in the zero line, so the three-phase electricity does not use the zero line.
