Claims16
A system, comprising:
- an electrical conductor for power transmission;
- a measuring probe for detecting an electrical field surrounding the electrical conductor, the measuring probe passing through a wall, the measuring probe being rod-shaped and situated proximate to the electrical conductor;
- and
- a fairlead seal for sealing a fairlead of the measuring probe, wherein the fairlead seal surrounds the measuring probe with form fit in an area of the fairlead, and the fairlead seal has at least one radially protruding insulating rib encircling the measuring probe at a circumference of the measuring probe, and the fairlead seal has a hydrophobic surface at least in the area of the insulating rib such that the insulating rib sheds water falling from the electrical conductor away from an exposed surface of the measuring probe.
