Example: Cable Reference Direction - Disconnected from an Installation
Consider an example where a cable is disconnected from the installation / geometry.
The cable cross section orientation is indicated
by:
- dotted green line: vector
- dotted blue line: vector
- solid dark blue line: cable reference direction
Note: CADFEKO tries to orientate the
vector at the start of the cable path to align
with the cable reference direction automatically using the constraint that the
and
vector must be perpendicular to the cable path.

Figure 1. Cable reference direction with an installation present.
- No bonding impedances are allowed in the harness, for example, no termination /
interconnect
circuit connections to the installation.
- All cable paths should at least have two signals in the outermost problem.
- All cable paths in the harness should have an orientation vector defined (if that path does not have any nearby geometry / installation).
