Abstract
The idea of a Solid-State Transformer (SST) has received much interest recently and is being thoroughly explored for use in the electrical system by replacing the traditional low-frequency transformer (LFT) using high-frequency isolated ACAC conversion. The SSTs are able to offer several additional functions than the traditional LFT. As the SST concept becomes popular among the power system, the safety of the system becomes vulnerable. The SST is made of a collection of several power electronic switches which has less reliability in general. Several kinds of faults can be caused by this issue like overcurrent, overvoltage, and overtemperature. These main issues are generally discussed in this paper to give a better idea of the faults that can happen in the system due to the integration of SSTs. In order to protect the SST a specific protection scheme must be needed. Further, it must have the ability to protect the system from disturbances coursed by the integration of SST. There are several protection schemes are available in the literature for the purpose of protecting the SST. Most of them are designed based on traditional power systems which are equipped with the LFTs. A few of them are discussed in this paper with their schematic diagrams to give a better understanding. The main focus of these protection systems is the protection of power electronic switches which will discussed in detail in this paper. Therefore, this paper will be a huge benefit for the researchers who are working on designing the protection systems for SST. Further, this paper will highlight the research areas that need more focus from a protection perspective.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
