A description of the nature and origin of power disturbances is provided, followed by theory on the various parameters that impact power quality.

The recommended practices described are intended to enhance equipment performance while maintaining a safe installation. Jabalina cilndrica de acero-cobre y sus accesorios. The main objective is to provideconsensus recommended practices in an area where conflicting information and conflicting design philosophies 2184- dominated. 22184-1 standard establishes minimum electrical protection requirements intended to mitigate the disruptive and damaging effects of lightning and ac power faults at telecommunications 214-1 entrances to customer structures or buildings.

It addresses the baseline grounding and bonding requirements for telecommunications equipment, the associated dc and ac power facilities, and the interfacing of co-located telecommunications systems installed in central offices and similar facilities. Information on telecommunications system power protection as well as grounding, industrial system grounding, and noise control is included.

Communications towers and the ifam structures, by nature of their outdoor location, are often subject to disturbances form lightning. Telecommunications service providers employ electrical protection equipment and bonding and grounding techniques at the network appearance to reduce the effects of such disturbances. This standard provides the minimum electrical protection, grounding, and bonding criterianecessary to mitigate the disruptive and damaging effects of lightning.

Materiales para puesta a tierra.

Telecommunications central offices, data centers, electronic equipment enclosures EEEand similar type facilities are often subjected to disturbances from lightning and ac power link faults, either directly or indirectly, through the communications cables and ac power facilities that serve them.

This standard provides minimumapplication of electrical protection, grounding and bonding, as a function of the electrical environment. Telecommunications network plant is often exposed to such disturbances due to its physical location and frequent joint-use or joint right-of-way installations with power utility facilities and may carry a portion of these disturbances to the network appearance at a customer structure or building.

Finally a selection of case studies are presented to support the recommended practices presented throughout the book. This standard defines and describes the grounding and bonding topologies commonly used for the installations of network telecommunications equipment in central offices and similar type facilities.

Telecommunications outside plant, by nature of its outdoor location, and frequentjoint-use or join right-of-0way installations with power utility facilities, is often subject to disturbances from lightening and ac power line faults.

Disturbances from lighting and ac power line faults may be disruptive to telecommunications service and may also result in damage to the telecommunications plant and equipment. Recommended power protection equipment and wiring and grounding system design practices 2184-11 presented. Grounding and bonding information from other standards related to telecommunications equipment is also included.
