Abstract
Insulator for a cable termination assembly comprising: a main body of insulating material extending along a longitudinal direction X and having a cylindrically symmetrical shape with a first longitudinal end and a second longitudinal end opposite to each other, said main body being adapted to be fitted on a power cable; a ring-shaped electrode made of a mesh of conducting material integrated in the main body at a predefined distance from the first end, said ring-shaped electrode being configured to be connected to an external voltage detector.
Claims20
An insulator for a cable termination assembly comprising:
- a main body of insulating material extending along a longitudinal direction and having a cylindrically symmetrical shape with a first longitudinal end and a second longitudinal end opposite to each other, the main body being configured to be fitted on a power cable;
- and
- a ring-shaped electrode made of a mesh of conducting material integrated in the main body at a predefined distance from the first longitudinal end, the ring-shaped electrode being configured to be coupled to an external voltage detector.
A cable termination system comprising:
- a power cable;
- an electric field control element fitted to the power cable;
- and
- an insulator comprising:
- a main body of insulating material extending along a longitudinal direction and having a cylindrically symmetrical shape with a first longitudinal end and a second longitudinal end opposite to each other, the main body configured to receive the power cable, and
- a ring-shaped electrode made of a mesh of conducting material integrated in the main body at a predefined distance from the first longitudinal end, the ring-shaped electrode being configured to be coupled to an external voltage detector, wherein the insulator is coupled to the electric field control element so as to surround it at least partially.
A method for monitoring a cable termination assembly comprising:
- coupling a ring-shaped electrode of an insulator for the cable termination assembly applied on a power cable to a voltage detector, the insulator comprising:
- a main body of insulating material extending along a longitudinal direction and having a cylindrically symmetrical shape with a first longitudinal end and a second longitudinal end opposite to each other, the main body comprising an inner opening for receiving the power cable, and
- a ring-shaped electrode made of a mesh of conducting material integrated in the main body at a predefined distance from the first longitudinal end, the ring-shaped electrode being configured to be coupled to an external voltage detector;
- detecting a voltage signal with the voltage detector;
- and
- analyzing the voltage signal through the voltage detector and based thereon determining if the power cable is under voltage or detecting the presence of partial discharge.
