It's That Time of the Year for Con Edison

  With the last of this year several feet of snow, which has all but melted by now Con Edison Is checking their underground transformers. As in the photo below the run off of water from the melting snow has carried snow melting salt which can damage the insulation. 

  The FDNY was called to this Con Edison underground transformer site which was belching up smoke from below ground. Firefighters roped off the area, and Con Edison came the next morning to repair the damage. The response to my question of how often this happens, was 'It happens every spring thaw when the snow melts'.
