Trainees personally experience step-voltage shock, learn how it arises, where it is likely, why it happens and how to leave the danger zone correctly. Their step length and distance from the drop point are mapped onto a 3D scene in real time. Functions: shock and escape experience (walking normally triggers shock; jumping on one foot or with feet together does not); barefoot or shock-bracelet modes; trajectory synchronization on a large screen; real-time current/voltage display; infrared positioning; eight linear voltage steps; leakage, earth, current-limiting and auto-recovery protection; AI assessment.
