This system simulates the potential distribution created when a wire falls into water and demonstrates the shock a person receives when approaching the drop point, teaching that wading shock depends not only on current, voltage and distance but also on ion density and contact area. Functions: wading safety theory; scenario experience; simulated wading shock (puddle, tree leak, transformer leak); shock bracelet experience; real-time scenario display; leakage and earth protection; AI assessment with face recognition.
