description This paper presents a power transformer model to evaluate differential element performance. The paper analyzes transformer energization, overexcitation, external fault and internal fault conditions with this model. Test results with an actual transformer validate the model. The paper includes a guide for properly selecting current transformers for differential protection applications. Accurate power transformer modeling and proper current transformer selection leads to improved transformer protection.
