Abstract
A high voltage measuring device is disclosed for measuring the voltage between two spaced-apart points using a poled optical fiber that is extended between the points and subjected to an electric field associated with the voltage. A control unit of the device has a light source, which transmits light into the fiber. The device also has a detecting unit for receiving light transmitted through the fiber and for generating a signal (S ) corresponding to a change in refractive index of the fiber caused by the electric field.
