If you want to get a visit from the power company as urgently as possible, just call them and say the phrase "floating neutral" (of course, they'll be mad at you if it's not true). Our neighbor's (poorly-attached) service mast came down a few weeks ago, causing a short that burned out the shared wires that connect both them and us to the transformer. After the initial event (complete with loud pops, sparks, flames...), our power actually came back on; but I insisted on keeping our main breakers turned off until the power company made their repairs. Turned out to be a wise move, as we indeed had a floating neutral.
