Abstract
An electrical contact avoidance device comprises an inductor plate directly or capacitively coupled to the user and coupled to a detector circuit which derives a DC signal corresponding to a voltage induced in the user's body by a radiated high voltage electrostatic field. A comparator compares the DC signal with a reference signal representing the potential difference between the inductor and reference plates, and activates an alarm if the detected signal exceeds a preselected reference level.
