Performing Analysis of Current Transformer in Short Circuit and Open Circuit Conditions By ANSYS@Maxwell

Calculation of the design parameters current transformers (CTs) is very complex due to their magnetic and thermal properties, complexity structure, different ferromagnetic properties materials nonlinearity B-H curve core material. The secondary output these used for both measurement protection circuits. Therefore, AT's accuracy must be good precise. In this study, transformer modeled as 2D using Finite Element Method (FEM). ANSYS@Maxwell program, which realizes a solution based on finite element method, has been in analysis transformer. Analyzes were carried out under open short circuit conditions. From results obtained from analysis, scattered electromagnetic flux distribution occurred transformer, caused CT erroneous. it observed that unwanted operating conditions occur circuits..
