The invention relates to an open-type current transformer and a manufacturing method thereof. The open-type current transformer comprises a shell and annular iron cores, wherein the shell comprises an upper shell body and a lower shell body, the upper shell body and the lower shell body are movably connected, the iron cores comprise an upper iron core accommodated in the upper shell body and a lower iron core accommodated in the lower shell body, a secondary winding is wound on the lower iron core, and a compensation winding is arranged on the upper iron core. According to the open-type current transformer, the compensation winding is arranged on the upper iron core without the secondary winding to compensate the secondary winding, so that various parameters of the secondary winding meet parameter requirements, the yield of products is improved, the requirements on iron core materials are reduced, the wire consumption of the secondary winding is reduced, the production efficiency is multiplied, and therefore,
