摘要： 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 further comprises the connection of the cover section to the base section to form a passage through which a high voltage conductor may extend.

摘要： An electrostatic shield for controlling the electrostatic field between a high voltage conductor and a low voltage conductor in an instrument transformer is provided. The instrument transformer has a current transformer and a voltage transformer. The current transformer has a split core which includes a first core segment and a second core segment. When the first core segment adjoins the second core segment, a current transformer is formed, having a core formed from the first and second core segments. The high voltage conductor runs between the first and second core segments of the current transformer. The first core segment is encapsulated in a polymer resin and when encapsulated, forms a first encasement. The second core segment has a low voltage winding mounted thereon. The electrostatic shield is disposed between the low voltage winding and the high voltage conductor. A second encasement is formed by encapsulating the electrostatic shield, low voltage winding and second core segment in a polymer resin.
