Abstract
The invention relates to a simplified and cost-effective apparatus for injecting signals into electrical power lines at the high-voltage or medium-voltage level. A coupling unit which is simple to assemble and is protected against direct contact is proposed, in which the connecting cable 9 is integrated in the housing 10 of the coupling capacitor 8. In the region where the conductor 20 passes through the grounded housing 10 of the coupling capacitor 8, the electrical field is reduced by means of the housing wall having a special shape 10a. A smooth field distribution is achieved by suitable rounding of the formed region 10a which is provided for the insertion of the connecting cable 9.
