How to Select Surge Protection for Data, Signalling and Control Circuits?
Where should the SPD(s) be installed?
Communications devices are at risk from transients being induced onto the interconnecting signal lines. The use of surge protection barriers, installed at either end of the lines, provides cost-effective protection. Communication or signal lines that enter or exit the building pose the highest risk. In such circumstances, protection devices should be installed at the point-of-entry or at the equipment termination itself. Internal wiring which extends more than 10 to 15m should also be protected. Twisting or shielding of cables provides a level of protection, however, this should not be regarded as sufficient for the sensitive interfaces that characterize today’s communication devices.
