Abstract

The report describes a 110kV active optical fiber current transducer (AOCT). The transducer is different from the passive one, because a special power supply is designed for high-voltage unit and none optical crystal or magneto-optical fiber is used. The AOCT consist of three parts: a high-voltage measurement unit, a low-voltage signal processing unit and an optical fiber link which connects theses two units. As a result, the safe protection is reliable for the low-voltage equipment and the operation staff. Compared to the conventional current transformer, the advantages of the AOCT are high accuracy, low cast, small size, wide bandwidth, excellent dynamic characteristics and immunity from electromagnetic interference. The 110kV AOCT has been tested and its accuracy could achieve ±0.2%.
