Power and data cables should not be run in parallel for long distances, and
ideally should be installed in separate conduits. Power and data cables
should intersect at 90 angles when necessary to reduce inductive coupling.
Shielded/screened cabling can optionally be used. The cable shield should
be grounded at a single point to avoid the generation of ground loops.
2.7.4 Transient Suppression
RuggedCom does not recommend the use of copper cabling of any length for
critical real-time substation automation applications. However, transient
suppression circuitry is present on all copper ports to protect against damage
from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1
conformance. This means that during the transient event, communications errors
or interruptions may occur but recovery is automatic. RuggedCom also does not
recommend using these ports to interface to field devices across distances which
could produce high levels of ground potential rise, (i.e. greater than 2500V)
during line to ground fault conditions.
