FaultXformer: A Transformer-Encoder Based Fault Classification and Location Identification model in PMU-Integrated Active Electrical Distribution System

Researchers developed FaultXformer, a Transformer-based AI model that achieves 98.76% accuracy in fault classification and 98.92% accuracy in fault location identification in electrical distribution systems using PMU data. The dual-stage architecture significantly outperforms traditional deep learning methods like CNN, RNN, and LSTM, particularly in systems with distributed energy resources integration.
