Paper Abstract

Optical Current Transducer (OCT) is a ne kind of transducer applying in electric power measurement system. This paper analyses the questions of temperature offset and noise affection in measuring DC current with OCT. The solutions to these questions are described in this paper. One is adopting AC modulation technology to overcome temperature offset. The other is an adaptive filter algorithm which is used in OCT to refrain noise. It is proved by experiments that the two methods are effective and can improve the measurement accuracy.
