FIELD CONTROL ELEMENT FOR A HIGH-VOLTAGE CABLE ACCESSORY AND METHOD OF OPTICALLY MEASURING PARTIAL DISCHARGES

摘要

The present invention relates to a field control element for a high-voltage cable accessory. The present invention further relates to a high-voltage cable accessory (200, 300, 400) and to a method of monitoring partial discharges occurring within an insulating part of such a high- voltage cable accessory. According to the present invention, said field control element (212; 304; 406, 408) comprises an electrically insulating material that is at least partly provided with a fluorescent dye, said fluorescent dye being configured to convert a first radiation generated by an electrical discharge into a second radiation with a wavelength that is longer than the wavelength of the first radiation. A high-voltage cable accessory (200, 300, 400) has an electrically insulating part that comprises at least one field control element (212; 304; 406, 408) according to the present invention and/or a further insulating element comprising a fluorescent dye.
