MOBIUSI INCThis dataset contains relay protection practice questions, answers, and explanations for electrical engineering, covering protection principles, fault identification, setting logic, secondary circuits, and substation operations. The web-text records are organized with fields such as knowledge domain, question type, difficulty, key concepts, and reasoning steps for targeted search and filtering. It supports supervised fine-tuning of power engineering question-answering models, knowledge coverage evaluation, and the development of learning support tools.
