| Abstract: |
| The advantages of Digital Opto electronic Instrument Transformer (DOIT) are presented. The DOITs are classified into two classes: active and passive. The principles of the active electronic opto electronic transformer, the passive Faraday effect opto electronic current transformer, Pockels effect voltage transformer and other types of passive DOIT are explained. The current DOITs abroad and in China are introduced. |
| Key words: digital opto electronic instrument transformer,current transformer,voltage transformer |
