Primary and Secondary ProtectionPrimary and Secondary Protection

Primary Protection

Primary Protectionfrequently comprises acombination of resistors andsurge arrestors and isusually located at thebuilding entry interface.

The task is to sufficientlyreduce the high-energyinterference distortion sothat they can be safelyabsorbed by the followingsecondary protection.

Primary

Protection

Secondary

Protection

ExchangeSubscriber

Secondary Protection

The secondary protection isnormally located directly at theappliance entry of the telecomequipment and has twoobjectives.1. It operates as a voltage limiter

which ensures that inter-ferences are absorbed orreduced to a level harmless forthe telecom equipment

2. It effectively suppresses highenergy level interferences
