Abstract
An instrument transformer for measuring properties of electricity in a power line is provided. The instrument transformer includes a cover section releasably secured to a base section. The cover section includes a first core segment encapsulated in a first encasement formed from a polymer resin. The base section includes a second core segment with a low voltage winding mounted thereto and a voltage transformer, all of which are encapsulated in a second encasement formed from a polymer resin. When the cover section and the base section are secured together, the first core segment adjoins the second core segment, thereby forming a current transformer having a core formed from the first and second core segments. A method for making the instrument transformer includes the connection of the cover section to the base section to form a passage through which a high voltage conductor may extend.
