The Analysis for the characteristics about the Digital Control CT & PT

디지털 제어형 CT 및 PT에 관한 특성 분석

Generally, instrument transformer of the core type have been used for measuring current. Because instrument transformer has defects, electronic instrument was appeared. Electronic instrument has many merit-linearity, small size, low cost, etc. Rogowski coil is typical electronic CT and R-divider is typical electronic VT. This paper is introduced a basic concept and theory of electronic current transformer, electronic voltage transformer.
