| Abstract: | According to the structural characteristics and measuring principle of OET722ACTZ current transducer installed in Guojiatun digital substation,an analysis is made on the factors which affect the measuring precision of the transducers.It is found that the change in signal output mode resulted in data synchronization problems and it is therefore proposed in this paper that data synchronization performance should become an important criterion to judge the precision of transducers.Field tests were also carried out to verify all performances of OET722ACTZ current transducers. |
