Common Mode vs. Differential Mode
Identifying the type of surges that may threaten a system is an important
part of selecting the appropriate levels and methods of transient protection.
Since each of the conductors in a data cable travels through the same physical
space, it is reasonable to expect transients caused by environmental or current
switching to be “common mode” that is, present on all data and ground
conductors within the data cable. In some installations, there may be another
source of unwanted energy to consider. If there are high voltage cables running
anywhere near the data cables, the potential for a fault condition exists as a
result of insulation failures or inadvertent contact by an installer. This type of
surge could contact any number of conductors in the data cable, presenting a
“differential” surge to the data equipment. Although the voltages and currents
associated with this type surge are much lower than the types of surges modeled
by ANSI or IEC, they have a particularly destructive quality of their own.
Instead of dissipating within several milliseconds, they can exist in a steady
state condition on the data network.
