Abstract: Voltage sensor (1) comprising a voltage divider (40) for sensing an AC voltage of a HV/MV power conductor (10). For adjusting the common overall impedance of the low-voltage portion of the voltage divider towards a desired impedance, the low-voltage portion (60) comprises one or more low-voltage impedance elements (110), a plurality of adjustment impedance elements (80) and a plurality of switches. In its connect state, each switch electrically connects an adjustment impedance element in parallel to at least one of the one or more low-voltage impedance elements (110). The overall impedance of the high-voltage portion (50) and the overall impedance of the low-voltage portion (60) of the voltage divider (40) are adapted such that, by bringing one or more of the switches (90) into their connect state, the voltage divider (40) has, for an AC voltage of between 5 and 25 kV phase-to-ground and a frequency of between 40 and 70 Hertz, a dividing ratio of 3077, of 6154, of 6769 or of 10 000.

Abstract: Sensored insulation plug (1) for being inserted into a separable connector in a power distribution network comprises a plug body (140) formed by a solidified insulating material (610), and a primary capacitor (150), operable as a high-voltage capacitor in a voltage divider for sensing the elevated voltage. The primary capacitor includes a high-voltage electrode (160) for direct electrical connection to the elevated voltage. A sensing electrode (170) of a tubular shape, embedded in the plug body (140), arranged around the high-voltage electrode, comprises a deformable mesh of conductive wires forming a plurality of apertures between the wires to allow portions of the insulating material (610) on opposite sides of the mesh to be mechanically connected with each other by insulating material in the apertures while the insulating material solidifies and thereafter. A dielectric formed by a portion (180) of the insulating material (610) is arranged between the sensing electrode (170) and the high-voltage electrode (160).

Abstract: An optical fiber connector for external connection to a telecommunications enclosure is described herein. The optical fiber connector has an assembly base having a first end and a second end, an optical connection portion disposed partially within the first end of the assembly base and a strain relief assembly disposed on the second end of the assembly base. The assembly base includes a body portion and a release portion which defines a release mechanism that causes the release portion to move relative to the body portion. The release portion includes at least one cam that is configured to release or disengage the at least one latch element when the release portion moves with respect to the body portion so that the optical fiber connector can be removed from the port of the telecommunication enclosure.

Abstract: A sensored insulation plug for a medium-voltage or high-voltage separable connector in a power distribution network of a national grid, and operable to insulate a connection element of the separable connector on elevated voltage and to sense the elevated voltage. The sensored insulation plug has an outer shape generally symmetrical about a plug axis defining axial directions and radial directions, and comprises a plug body formed by an insulating material, and a primary capacitor, operable as a high-voltage capacitor in a voltage divider for sensing the elevated voltage. The primary capacitor has a high-voltage electrode for direct electrical connection to the elevated voltage, a sensing electrode of a tubular shape, embedded in the plug body, arranged around the high-voltage electrode and extending, in axial directions, between a first axial edge position (B) and a second axial edge position (A), and a dielectric formed by a portion of the insulating material arranged between at least a portion of the sensing electrode and at least a portion of the high-voltage electrode. A shield electrode of generally tubular shape, embedded in the plug body, is arranged around the sensing electrode and extending in axial directions at least between the first axial edge (B) position and the second axial edge position (A), and comprises a protruding portion extending in axial direction beyond the first axial edge position (B), such as to enhance electrical shielding, by the shield electrode, of the sensing electrode against external electrical fields.
