igure 8 presents REX640 in a three-winding power transformer
application. The base functionality is enhanced with a power
transformer application package and the related three-winding
add-on package. In the example case, REX640 also manages
the on-load tap changer’s manual and automatic control. For
this purpose, the application package for OLTC control has
