Conjunto (100, 101, 102, 103, 200, 201) de alta tensión para el alojamiento de un cable (1, 22) de alta tensión con un conductor (11, 112) configurado para conducir corriente eléctrica de más de 1 A en tensiones por encima de 1 kV y un aislamiento (12, 122) de cable que rodea el conductor (11, 112), que comprende: - un aislamiento (2, 3, 32) que comprende una parte (3, 32) de control de campo que está configurada para rodear el aislamiento (12, 122) de cable al menos parcialmente; y - al menos un sensor (20, 21) de fibra óptica acoplado mecánicamente con la parte (3, 32) de control de campo que está configurado para detectar en el aislamiento (2, 3, 32) una deformación mecánica provocada en el aislamiento (2, 3, 32) por una descarga parcial eléctrica en forma de oscilaciones mecánicas con frecuencias en el intervalo de aproximadamente 10 kHz a aproximadamente 500 kHz. The high-voltage fitting comprises a conductor for conducting an electric current, a cable insulation (12) surrounding the conductor, an insulation (2) comprising a field control part (3), which is partially arranged to surround the cable isolation, and a fiber optic sensor (20) mechanically coupled with the field control part, where the sensor is arranged to detect a mechanical deformation in the insulation and to detect mechanical vibrations having frequencies of 10-500 kHz. The fiber optic sensor is a sound sensor, a strain sensor and/or a bending sensor and comprises an elastomer. The high-voltage fitting comprises a conductor for conducting an electric current, a cable insulation (12) surrounding the conductor, an insulation (2) comprising a field control part (3), which is partially arranged to surround the cable isolation, and a fiber optic sensor (20) mechanically coupled with the field control part, where the sensor is arranged to detect a mechanical deformation in the insulation and to detect mechanical vibrations having frequencies of 10-500 kHz. The fiber optic sensor is a sound sensor, a strain sensor and/or a bending sensor, comprises an elastomer, and is partially embedded in the field control part and/or is arranged on a surface of the field control part. The insulation further comprises an insulating region that surrounds the field control part and is partially embedded in the fiber optic sensor. An independent claim is included for a method for detecting a partial discharge in an insulation of a high-voltage fitting.
