Abstract

Apparatus, voltage detector for industrial electrical lines and installations, allowing to discriminate different voltage levels, comprising a warning element, capable of emitting an acoustic or optical signal and linked to its own source through a control system sensitive to an electrical potential externally of determined magnitude (threshold) applied to an input electrode (feeler), characterized in that said control system comprises at least two different detection circuits and sensitive to different thresholds of potential, the change of state being (blocked or driver) of each of said circuits under the influence of said potentials, capable of acting in a specific manner on at least one other circuit of the control system.
