Example: Cable Reference Direction - Connected to an Installation
Consider an example where a cable path is defined within a distance of from a ground plane.
- dotted green line: vector
- blue line: vector
- solid dark green line: cable reference direction
The cable reference direction is defined normal to the installation or ground (in the “up” direction) and is not pointing towards it. In the cable schematic the cable is connected to the installation and acts as a return path for the signal. No twist angle is defined along the cable path.
