From CNN,three power lines in Ohio wen't down an hour before the cascade.An alarm to indicate the stability of the grid was not working so they thought it was stable and didn't disconnect however they are still not 1OO% sure.They also said data was coming in so fast durring the first few minutes that it was't logged in a timely fashion.I'm sure somewhere there's a fault history file that will tell the story.According to our equipment we had a spike at 4:06 pm and then zero line volts at 4:07 pm.The system was even not at capacity when it happened so load was not a factor.
