    Transfomer Core size vs Power

    Hello questions for the experts, Is there a realationship between the core size of a transformer (single or three phase ) and its power rating? Please describe. thx

    remnant flux maximum values?

    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...

    Calculating an Adjustment angle from the Residual Flux

    Hello Gurus, I am looking at an algorithm that reduces the inrush in a 3 phase power transformer by using the controller switching method of a static transfer switch between two sources. To compensate for the remnant flux Br, the algo computes an adjustment in degrees that eventually gets added...
