File talk:Fukushima 1 transformer building reactors 5&6.jpg

I changed the name of the lines pictured to the Futaba line (550kV) The Yonomori line is 66kV and just a few feet away. I don't know why that line is there. It may have been used during construction. I have seen the Yonomori line labeled as if it supplied power to 5/6, but the plant already produces lots of power at 9.6kv, from the generators. Daiini also has a 66kV line and units 1-4 have a low voltage line that runs parallel to the first base line. Mystery to me. (MartinGugino (talk) 04:09, 15 March 2013 (UTC))

Futaba lines remained energized throughout the incident
