15kV Reactor Winding
15kV Reactor Winding
(OP)
Was wondering if you have a turn to turn fault on a 15kV dry-type reactor winding of lets say 10%, would that reduce the impedance of the reactor by 10%? Or is it a little more complicated than that.

100% - 10% = 90%
90% x 90% = 81%
100% - 81% = 19% drop.
In most cases it will be more complicated. You now may have an auto-transformer with the fault acting as a shorted winding. You may get saturation at lower through current levels. (premature saturation?)
