PROTON 206/308 V1 System Manual
This is not always possible but every attempt should be made to place the primary protection as close as
possible to the entry point of the cables into the building, shelter or equipment housing. Hence, the system
should be installed with lighting protectors. In addition, grounding (connection to earth ground) is very important
to protect the system.
Surge Protective Device (SPD):
A device that is intended to mitigate surge overvoltages and overcurrents of limited durations. It may consist of a
single component or have a more complex design, where several functions are integrated. It contains at least
one non-linear component. Primary protection is applied using an SPD to protect an interface of the equipment,
at the location where it diverts most of the stressful energy from propagation into the equipment. The SPD must
be accessible, removable and connected to equipotential bonding. The cost of using Gas Discharge Tube(GDT)/
Metal Oxide Varistor(MOV)/Fuses for equipment protection will be far more economical than the equipment
downtime and potential damage that could result from being improperly protected. Surge protection device
creates a short circuit and shunting the surge voltage to ground, when a preset voltage threshold is exceeded.
Inherent Protection:
Inherent protection is that protection which is provided at an equipment interface either by virtue of its intrinsic
characteristics, by specific design or by suitable protection components. Inherent protector is not a subsidiary
but an essential device because it usually operates earlier than the primary protector and protects the
components.
