| Abstract: | Based on the construction practice of 500 kV digital test unit and the dynamic simulation test,this paper researched the application of electronic transformer in engineering. The conclusion: both insulation and sample accuracy of 500 kV electronic instrument transformers fulfill the engineering demands. Compared with conventional transformers, electronic instrument transformers have relatively higher sample accuracy and better stability. A number of issues existing in the practices of electronic transformer engineering is proposed, and the solutions are given accordingly. |
