SEC’s main lines consist of three ‘phase’ wires. It is possible for one of these phases to be without power while the other two phases continue to provide electricity flow. It is also possible you are served by a tap line near the main line. In these cases, power can be interrupted to the tap line while the main line stays on. It is also possible your transformer has failed. If the tap is on and the transformer is not working, your power will be out while many or all of your neighbors’ power remains on.
