Beschreibung
Zusammenfassung:	The invention concerns an electrical accessory comprising: - a tubular conductor (43) through which a current-carrying conductor (32) can pass ; - at least one insulating layer (34, 36) disposed around the tubular conductor (43); - a voltage sensing element (38) forming a capacitive voltage divider to determine a voltage on the current-carrying conductor (32), comprising: ¢ a first capacitor (40) formed by the at least one insulating layer (34, 36) ; ¢ a second capacitor (42) electrically connected to a ground potential and to the first capacitor (40); characterized in that the first capacitor (40) comprises at least two insulating layers (34, 36) having a dielectric constant whose temperature dependency coefficient has opposite signs with respect to each other.
