ABSTRACT:
A post type oil filled current transformer having a U-shaped primary winding formed of a tubular conductor. An oil flow controlling hollow tubular member is disposed within the primary conductor. The tubular oil flow controlling member is vertically oriented and spaced from the internal wall of the tubular primary winding to define inner and outer coaxial paths permitting a downward flow of cool oil in the inner path within the tubular member and an upward flow of heated oil in the outer path between the tubular member and the inner wall of the primary winding.
