초록
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.
