Transformers are essential components in distribution systems, but they are susceptible to various fault currents, posing a significant challenge in terms of protection. This paper introduces a novel integrated design, referred to as a self-protective transformer, which ensures the transformer can withstand fault currents while safeguarding the power network. In this innovative structure, a saturated fault current limiter is directly integrated into the magnetic circuit of the transformer. During regular operation, the deep saturation of the FCL component of the structure introduces a minor impedance into the network, enabling it to operate as a transformer. However, during fault conditions, impedance is introduced to the fault current path, preventing a sudden surge in fault current while still maintaining transformer functionality. Our integrated design aims to protect transformers from fault currents, leading to decreased operation and maintenance costs, improved reliability, and user-friendliness of the equipment. The power rating of the transformer in this paper is 2KVA. To evaluate the effectiveness of this design, simulations are conducted using the finite element method (FEM), demonstrating the efficiency of the proposed approach.
