'AN IMPROVED DEAD TANK CURRENT TRANSFORMER TO REDUCE THE MAGNITUDE OF MAGNETIZING CURRENT AND LIMIT THE RATIO, AND PHASE ANGLE ERRORS'

摘要

The invention relates to an improved dead tank current transformer to reduce the magnitude of magnetizing current and limit the ratio and phase angle errors, comprising a copper or aluminum tube acting as a primary tube and circumscribing a top chamber, an insulator, and a bottom tank; one each incoming and outgoing terminals; the improvement is characterized in that the primary tube is split lengthwise to form two equal halves which are separated by an insulating layer and connected in series, and in that the two halves forming two turns / loops through the secondary cores of the transformer which doubles the ampere-turns on the primary side to reduce the ratio and phase angle errors.
