Abstract : 　With the development of voltage transducer for Shensi ±50 kV DC transmission project , the principle , construction , technical parameters and the response2time measuring method of the DC voltage transducer are introduced in this paper. The results show that it is the key point to use optic2electric coupling circuit and se2 lect the elements with high accuracy and high steadiness in order to improve the performance of the electronic isolation device and to re2 duce the error of the DC voltage transducer system.
Key words : 　DC; voltage transducer , optic2electric coupling ; electronic isolation device ; measurement
