Surge Protection For Telecom


Surge Protection For Telecom



Telecommunications systems rely upon critical equipment in order to not only provide coverage within specific areas to their customers, but also to provide communications capabilities through their interconnected network.  People rely upon cellular connectivity for their routine daily tasks as well as for critical communications during times of emergency.  Connectivity to emergency services is crucial at all times, and can be the difference between life and death in some instances.  The challenging aspect of this responsibility is the fact that the same kind of inclement weather conditions that can bring on the necessity for connectivity to emergency services, also has the capability to destroy the equipment that provides that connectivity.  One of the most common causes of damage to telecom systems as well as outages in connectivity is lightning strikes to the towers that provide the unobstructed signals to cell phones.  In order to provide the best and clearest signal possible, cellular towers must be the tallest structures within an area, ultimately making them a perfect target for lightning strikes.  Much of the equipment that is housed within these towers as well as the materials with which the towers themselves are constructed are also attractants of lightning.  When the strikes happen to the cell tower top, it has the ability to not only damage or destroy equipment located nearby but also equipment further away.  This is due to one of the inherent issues with the telecom business:  in order to provide an unobstructed signal you often must also position yourself as the best possible target for lightning.

In order to compensate for the obvious issues that come with these kinds of flaws  to a system, the telecommunications industry has utilized surge protection devices as a buffer between the lightning strikes and the equipment housed within the towers.  This is an attempt to minimize the amount of damage that is produced by inclement weather and the lightning strikes which must be expected.  There are various methods of attempting to lessen the risk exposure of a site to lightning strike, overhead shields and lightning rods being examples, but it must be expected and predicted that there will be a certain amount of lightning strikes to the towers themselves every time there is a thunder storm in the area.  The damage that will be produced by the lightning strike can be mitigated through surge protection equipment.  The damages that will generally be found outside of the strike point are usually based on the electrical surge that is produced by the strike itself.  This surge overwhelms the circuitry of the computerized equipment, and is able to travel along power lines that interconnect these devices.  These surges are stopped in their tracks by surge protection equipment installed along the lines that interconnect these devices.  Through a redundant and effective installation of surge protection devices, the amount of predictable damage to equipment as well as the outages that will be expected as a result of this damage can be brought to a minimum.  The integration of surge protection equipment therefore is critical to the ongoing functionality of telecom systems.
