Abstract: A three phase core form transformer for use in a three phase dual dynamic stabilizer system that provides reactive power compensation. The transformer has a three legged magnetic core, a plurality of primary windings corresponding to the phases, two auxiliary secondary windings per phase that are wound to provide first and second common bifilar portions, and a plurality of principal secondary windings corresponding to the number of primary windings. The first common bifilar portion, the principal secondary winding, the second common bifilar portion and the primary winding are placed coaxially and radially adjacent, in the recited order, starting from each leg of the magnetic core.The primary windings are connected in delta. The principal secondary windings and auxiliary secondary windings are connected in a forked wye wherein one auxiliary secondary winding of each of the other two phases is electrically connected to the free end of each of the wye connected principal secondary windings.
