Binary voltage indicator
First Claim
1. A binary voltage indicator comprising a first electrode as part of a first conductor, wherein a first voltage can be applied to said first conductor, a second electrode, arranged at a distance from the first electrode, a photoactive layer attached to the first conductor and consisting of a light-emitting or light-absorbing material which changes its emissivity or reflectivity under the influence of an electric field generated by the first voltage.

Abstract
The invention is concerned with a binary voltage indicator for use with high- or medium voltage equipment. The indicator comprises a photoactive layer (5) which changes its reflectivity or emissivity when subjected to an electric field and which is applied directly onto the surface of a conductor. The photoactive layer is based on materials as used for low-voltage displays, such as electrophoretic films.

10. Use of a photoactive layer consisting of a light-emitting or light-absorbing material which changes its emissivity or reflectivity under the influence of an electric field as a binary voltage indicator attached to a first conductor and a second electrode arranged at a distance from the first electrode, and indicating the presence or the absence of a voltage being applied to the first conductor.
