ABSTRACT:
The voltage presence indication device comprises a collector electrode (2) designed to have at least one capacitive connection (5) with an electrical ground (6) or a capacitive connection (3) with an electrical conductor (4) to be monitored, and display means (7) connected to said collector electrode (2) to indicate the presence of an electrical voltage in said electrical conductor to be monitored. The display means comprise at least one multilayer device (11). The multilayer device comprises a light-emitting layer (12) arranged between a first insulating layer (13) and a second insulating layer (14), a first conducting layer (15) arranged on the first insulating layer (13) and connected to said conducting electrode (2), and a second conducting layer (16) arranged on the second insulating layer (14). An electrical apparatus comprises such a device.
