    The current transformer model developed is based on the proposal made by "Power System Relaying Commttee (PSRC)", the IEC 60044-1 and 60044-6 standards and other technical documents. Therefore, this model proposes to combine the strengths of the PSRC model and IEC standards to verify, select, and valdate current transformers used n power systems as the primary element that wl delver information to protection relays. EMTP/ATP was used as simulation platform through ts abity to create programmng blocks (Models function) and use TACS functions. Wth the digital model, t is possible to capture nformation of power system and delver the results to analyze waveforms at the output of a current transformer. It is also possible to verify mportant sensitivities which are shown n the ast part of the document.
