Patent ID: 7459901

Claim:
A voltage presence indication device comprising: a collector electrode designed to have at least one capacitive link with an electrical ground or a capacitive link with an electrical conductor to be monitored; and a display means connected to said collector electrode to indicate the presence of an electrical voltage in said electrical conductor to be monitored; said display means comprising at least one multilayer device comprising: a light-emitting layer arranged between a first and a second insulating layer; a first conducting layer arranged on the first insulating layer and connected to said collector electrode; and a second conducting layer arranged on the second insulating layer; said display means further comprising at least one of the following: (i) the first conducting layer is directly electrically connected to the collector electrode, or (ii) the second conducting layer is directly electrically connected to the electrical conductor, or (iii) the second conducting layer is directly electrically connected to an electrical ground.
