transformers knock high voltage down to a usable level for a facility--or a housing development for example. i'm sure just about everyone hear has heard one blow before, sounds like an explostion...evidently their electrical problems were larger than first realized. i can see why they'd cancel a day-those things aren't like changing a battery, or going out and hitting your breaker box to reset stuff...but you would think they'd have known earlier than when they finally announced.
