WINONA, Minn. – Something looked and sounded really wrong. An electrical transformer up a pole in an East Side alley was smoking, arcing and it sounded like boiling. People on the 200 block of Chestnut Street called 911. This was about 6:50 p.m. Firefighters blocked the alley to keep foot and vehicle traffic back and called Xcel Energy, the utility that owned the transformer. An Xcel crew identified issue and shut the unit off.
