remnant flux maximum values? 4

Status

I have a question for the experts,

I read in a couple of white papers that the remnant flux Br inside a Xformer is the value of the last flux before d-energizing as it takes days to decay. My question is if we d-energize the Xformer at B(t) = Bmax =1.0 PU then the Br should equal 1.0 pu?? However according to the BH curve and some white papers the Br-max is around 0.7 P.U never to reach 1.0pu. Any explanation to this?


thx
