LIGHTNING AND SURGE PROTECTIONFOR EQUIPMENT INBUSINES PREMISES AND DOMESTIC USEHouses contain now numerous electric and electronicequipments with more complex and important functions.Big electrical appliances such as washing machines orfridges are robust and can withstand transient overvoltageswith no apparent harm at short term. Still their componentsmay suffer degradation or detriment. This damage ismore evident in electronic equipment such as computersor TV sets which peripherals are becoming more costlyand sophisticated. Besides, these accessories are ofteninterconnected thus increasing the probabilities of beingaffected by overvoltages. Houses with automated servicesusing domotics are even more exposed, since a computerfailure can lead to severe harms due to the controlledappliances.

Business premises have similar problems. Telecommuni-cations, electronic systems and security devices areessential and they are often interconnected. In many ofthese premises there are internal computer networksconnecting even equipment placed inside differentbuildings. Data lines and their connected equipment aredesigned for very low voltages and therefore surges

caused by lightning can producethem serious damages.

Even if the building is providedwith a proper external lightningprotection system, surges canenter the equipment through power supply, telephoneor TV lines or through the earthing system. These linescome from outside the structure so lightning electromag-netic pulses may affect them, both a direct strike inter-cepted by the external lightning protection system or adistant discharge.

Aplicaciones Tecnológicas, S.A. has designed the basicset for an efficient surge protection of most usual domesticelectric and electronic equipment, easy to install andwith an optimized cost. They are a barrier for lightningcurrent at each of the lines connecting the externalenvironment with your house or premise and yourequipment.

PROTECTION OF POWER SUPPLY LINES

Efficient protection for analogical an ADSL telephone lines,containing coordinated protection for one pair of lines.

• Protection for telephone lines and also for the digital and analogicalequipment connected to these lines (fax, modem, etc).

• Discharge takes place in an internal encapsulated element, with noexternal flash.

• Both common and differential modes of protection.• Low residual voltage.• Very fast response.• Connection with screw pressure, which provides better lightning

current withstanding capacity than usual telephone connectors.

ATFONO SPD has been tested in oficial, independent laboratories,obtaining their characteristics according to relevant standards.

PROTECTION OF TELEPHONE LINES

TEMPORARY OVERVOLTAGESATCONTROL/B protectors actuate when detecting a temporaryovervoltage, triggering the connected shunt release (S1,S2). This one disconnects then the associated Main CircuitBreaker (MCB), thus protecting down-stream installedequipment.

The temporary overvoltage warning system is formed by 2 light indicators: green (correct power supply) and red(overvoltage). It is provided with a test button for checking if the installation has been properly made.

TRANSIENT OVERVOLTAGESATCONTROL/B protectors also actuate when detecting a transient overvoltage, driving the current to the earth andreducing the voltage to a level that does not damage the connected equipment. Tested and certified in official andindependent laboratories.

PROTECTION OF COAXIAL LINES

PROTECTION OF DATA LINES

Due to their placement, aerials are one of the mostexposed elements to lightning discharges. Even whenan external lightning protection system exists, thedischarge secondary effects can affect the TV or RFsignals.

ATFREQ Surge Protective Devices protect the signal cable deriving the induced and conducted surges to the ground,thus avoiding damages to the communication and TV equipment and to the connected devices (DVD, video,decoders, home cinema sets, etc.)

• Optimum coupling with imperceptible losses.• Small attenuation in the signal even for very high frequencies.• Short response time.• Discharge takes place in an internal encapsulated element, without external flashes.• Small size.• Specific connectors for each application.

ATLAN SPDs are specially designed to avoidfailures in data transfer between equipmentsinside the same network. They protect the inputof the electronic circuits of the network cardsagainst harms due to transient currents.

ATLAN UNI RJ-RJ is a protector with RJ45 inputand output connectors, with a withstanding currentup to 2kA for every pair of lines.

It is designed to protect individually every singleequipment connected to the computers network.

EXTERNAL PROTECTIONThe installation of an external lightning protectionsystem avoids direct impacts on the structure andthe pass of the lightning current through theequipment.

Aplicaciones Tecnológicas, S.A. recommends theinstallation of an Early Streamer Emission airterminal DAT CONTROLER® PLUS characterizedby its response to lightning approach, going aheadany other element within its protection area andthus driving lightning current to earth through asafe path.

The installation of a Lightning Protection System with ESE Air Terminals must follow thestandard UNE 21186 or equivalents. Basic installation rules are the following:

• The lightning air terminal should be installed at least two meters higher than any other element withinits protected area.

• Each air terminal should be connected to the earthing with a down-conductor, placed preferably outsidethe structure. In case of buildings or structures with a height over 28 meters, or if the horizontal trajectoryof the down-conductor is larger than the vertical, then two down-conductors are needed.

• The down-conductor should be installed providing that its routing is as straight as possible along theshortest path without sharp bends or upward sections

• 3 fixings per meter should be installed along the down-conductor.

• The down-conductor should have a minimal section of 50mm2. Due to the impulse nature of lightningcurrent, flat conductors (tapes) are preferable to round conductors since the surface is larger for thesame section.

• Down-conductors should be protected from mechanical hits by installing ground guard tubes up to aheight of 2m above ground level.

• Earthing resistance value measured using conventional equipment should be lower than 10Ω.

• All earthing should be bonded to each other and to the general earthing ring.
