Abstract

Problems of correct estimation of metrological characteristics of current transformers based on constructional data and working conditions are of great importance. Applying the commonly known equivalent circuit of the current transformer requires its parameters to be determined correctly. A method for determining the equivalent circuit parameters of a current transformer, based on its field models, is shown in this paper. The results obtained using field computation and real‐life model tests are compared.
