6 Technical Reference Overview Protection systems in the communications network The importance of overvoltage protection has increased considerably over the past years. On one hand, this is due to growing demands placed on advanced communications systems that increasingly support voice, video and data transmissions. On the other, the deployment of electronics further into the network has resulted in miniaturisation with an increased integration density and hence reduced electrical strength. Connection and distribution technologies from ADC KRONE set a global standard and are supplemented by a powerful and flexible portfolio of protection solutions. Individual protection possibilities enable an optimum cost-to-benefit ratio and ensure maximum economic efficiency for the user. Technical Reference Applications of overvoltage protection Protection systems are used wherever communication lines are distributed and connected. Overvoltage protection fulfils various requirements, depending on the type of installation to be protected. In conventional switching equipment, overvoltage protection is used primarily to protect people. In highly sensitive electronic switching equipment installations, however, comprehensive protection measures are necessary in order to protect not just people, but also the valuable installation itself. Overvoltage is undoubtedly the primary cause of faults, i.e. interference caused by electrical energy disturbances in communication lines. The term overvoltage often calls to mind thunderstorms releasing vast amounts of energy. However, even static discharges, which may appear to be harmless, can seriously affect signal transmission or even paralyse entire networks. Overvoltage in supply lines for centrally controlled process management and control systems can sometimes lead to immense damage and costs into the millions, or even to irrecoverable losses. Different forms of overvoltage Although the different forms of overvoltage have basically remained unchanged for many years, their causes and effects are subject to change. Overvoltage can be caused not only by reproducible interferences, but also by impulses that occur randomly. Reproducible excess voltages caused, for example, by capacitive or inductive switching, are often easy to localise and suppress. In order to achieve efficient protection against excess voltages caused by non-reproducible interferences, a range of standards and recommendations can be adopted with a view to causes, duration and injection of such interferences into the system. Overvoltage in communication networks is usually the result of electromagnetic interference, equalising currents between different earth potentials or network short circuits. This is caused by switching operations on neighbouring lines, the indirect effect of lightning or natural forces, or by human error. The direct effect of lightning on distribution equipment is an exception, because this type of equipment is usually installed indoors or in enclosures. The massive amount of energy involved in direct lightning strikes requires separate protection concepts and structural measures. Apart from direct lightning strikes, however, interference by one of the following phenomena is more often than not the cause of damage to or destruction of communication systems: Indirect lightning impact Electromagnetic interference Inductive or capacitive effects Electrostatic discharge Contact with live power lines These conditions often represent a high degree of danger to human life. w w w. a d c k r o n e. c o m ( 0 )

7 Technical Reference Overview Recommendations for the application of protection measures Overvoltage protection devices consist of components or protective circuits that limit interference to permissible values. Overvoltage protection devices must adapt to regional and local requirements. These requirements include operating conditions on the line and the protection requirements that result from the specific application area. Graded protective circuits with secondary protection elements should be used for incoming circuits on the exchange side and for terminal equipment (telephone, fax, modem), because in addition to personnel safety, sensitive electronic systems must also be protected. High voltage protection is usually sufficient for the line. In the event that active components are installed in a cross-connection cabinet, graded protective circuits are also recommended. Costs and benefits for the user When selecting suitable overvoltage protection modules, the cost-to-benefit ratio is of interest. The cost of installing protection modules contrasts favourably to the increased availability of the communication network and lower repair costs. An optimum selection on the part of the network operator results in minimum costs with maximum economic efficiency of the equipment. The extent of protection measures is based on the requirements and specifications from the network operator or the equipment manufacturer. In the idealised diagram shown here, the cost minimum is the point where the two curves meet. In order to protect personnel, applicable standards and regulations for setting up and operating telecommunications networks must also be observed. Technical Reference The applicable standardsand/or regulations for setting up and operating telecommunication networks must also be observed to protect personnel w w w. a d c k r o n e. c o m ( 0 )

8 Technical Reference Overview Technical Reference 02 / BE P ro t e c t i o n S y s t e m s Operating conditions ADC KRONE s range of protection system products is designed to meet the needs of our copperbased connection and distribution systems. In most applications, the protection modules are electrically equivalent; however, they are not necessarily compatible in their contact and protection behaviour. Basic differentiators include: Operating behaviour of the system to be protected Overvoltage protection requirements (electrical and mechanical) e.g., requirements facing the permissible impulse current or the permissible AC discharge current. The network operator s specifications must be observed when designing the protection modules. The LSA-PLUS, LSA PROFIL or MDF 71 connection system used Requirements for protection for a single pair, or an entire module Furthermore, protection equipment and systems must be designed to meet the needs of the following network conditions. Before the planning phase begins, the requirements for the protection system must be examined together with the operating conditions. An over-designed protection system rarely leads to damage. However, it does impact the economic efficiency of the equipment. Over-designed protection also means an increase in repair costs and poses a personnel risk. Installation takes place after the distribution equipment has been set up. Retrofitting existing equipment is, in most cases, not a problem if LSA-PLUS and LSA PROFIL systems are installed. Network condition Selection condition Protection module Operating voltage < Response voltage Voltage resistance of the equipment to be protected > Impulse response voltage Nominal current < Nominal current Cut-off frequency (transmission rates) < Cut-off frequency Aside from the electrical characteristics, the conditions of the interface with the distributor system and, if necessary, the housing dimensions must be taken into consideration at the earliest possible stage. The following protection modules are available for the LSA-PLUS Series 2 blocks and for LSA-PLUS NT Protection Modules LSA-PLUS Distribution Blocks Jumpering with protection element in place Magazines Connection or disconnection no 1-pair ComProtect A series Connection or disconnection yes 1-pair ComProtect B series Disconnection or switching yes 1-pair ComProtect H series Disconnection or switching yes 1-pair ComProtect NTP series Disconnection or switching no w w w. a d c k r o n e. c o m ( 0 )

9 Technical Reference Overview Operating conditions Distribution modules with disconnection, switching and connection contacts can be used with ADC KRONE protection components. Disconnection and switching modules permit the insertion of serial protection components into circuits; connection modules only permit parallel contact access. 02 / BE P ro t e c t i o n S y s t e m s Selection Regardless of the series and circuit used, overvoltage protection components are all based on the same working principle: any excessive voltages are discharged to earth. Depending on the component, the energy consumption in the protection device is relatively small. One precondition for this is the protection component s low-resistance earthing. In line with signal potentials, a distinction is made between three-point and five-point protection. For connection modules, only threepoint protection is possible. Five-point protection (components in the signal path) is recommended for use with switching modules. Once the protective plug is removed, the contact in the module is open and possible faults cannot make their way to the downstream network. Fivepoint protection can also be implemented using disconnection modules. ADC KRONE supplies various protective circuits: Three-point protection: pure overvoltage protection (high-voltage or secondary protection) Five-point protection: overvoltage protection combined with current protection Five-point protection: graded protection (high-voltage and secondary protection with current protection) Components designed for single-pair protection provide a safe and reliable solution in LSA-PLUS and LSA PROFIL distribution systems and have advantages over multiple-pair protection magazines for eight- and/or ten-pair modules. When a single-pair protection plug has to be removed, this does not mean that the entire module (all eight or ten pairs) is then left unprotected. Partial or combined equipping of the modules is also possible. Because of their small dimensions, the most convenient protection plugs (ComProtect A, B and H series) also offer the option of switching and jumpering with protection components in place. All protection functions thus remain guaranteed at all times for both the communication equipment and maintenance personnel. Technical Reference The advantages of protection magazines for eight and ten pairs are mainly based on the fast set up and lower installation costs of a protection panel. When necessary, protection magazines for LSA-PLUS and LSA PROFIL can be installed in the distributor in combination with ComProtect components w w w. a d c k r o n e. c o m ( 0 )

10 Technical Reference Overview Technical Reference 02 / BE P ro t e c t i o n S y s t e m s Operating voltage/technical data The operating voltage of the system to be protected determines the protection plug s voltage class. The protection device must not be triggered during normal operation. This would not only destroy the protective circuit, it would also lead to interruption in signal transmission. The highest possible voltage class should be selected for the protection plug at least above the maximum voltage possible during operation (maximum operating voltage, including tolerance). The upper limit for selecting the protection plug s voltage class is determined by the maximum protection level permitted, i.e., the maximum input voltage that would not damage the downstream system components should overvoltage occur. The selection of components and switching configurations determines other electrical parameters for protective circuits. Properly designed and specified overvoltage protection components have a serviceable life of several decades and require no additional maintenance. ADC KRONE recommends that the nominal DC spark-over voltage of installed protection components be tested regularly. For safety reasons, the arrestors should be replaced if the protective circuit has been subjected to impulse current. Fail-safe Protective circuits with an integrated fail-safe feature are highly recommended. Components for overvoltage protection are usually designed only for pulse-shaped loads. Therefore, if permanent overloads are possible (e.g., mains contact), a safe short-circuit to earth must be ensured. Overloaded or overheated protection components would not only lose their protection function, they could cause fire or an explosion, leading to considerable damage and expense. w w w. a d c k r o n e. c o m ( 0 )

11 Technical Reference Overview Choosing protection components The mechanical interface where the protection components is going to be installed has to be taken into account. ADC KRONE offers a large number of complete magazine solutions and flexible single-pair protection plugs.

14 Technical Reference System Overview ComProtect protection plugs for LSA-PLUS and LSA PROFIL 1-, 8- and 10-pair solutions In applications in which valuable electronic equipment is used, simple three-point protection with overvoltage arrestors is not sufficient. Although overvoltage arrestors are in many cases essential components, the systems may require additional secondary protection. Such applications require highly flexible and efficient protection such as that offered by the modular ComProtect protection plugs. Technical Reference 02 / BE P ro t e c t i o n S y s t e m s Features Three- and five-point protection One-, eight- and ten-pair design assures flexible equipping of modules Support partial protection and retrofitting High-voltage, secondary, current and graded protection can be selected to meet specific requirements Additional measuring and disconnection points of various protection plugs enable work on the line without interrupting protection functions Compact design allows jumpering work on the distributor without removal of the protection components ComProtect solutions for LSA-PLUS and LSA PROFIL installations are installed after the necessary connection work has been completed. The earth bar, designed for eight or ten pairs, is fitted parallel to the module s cabling where interference is anticipated. Low resistance connection to back mount frames or profile rods are provided by the earth bar s forked contacts and/or by earth contact clips. (Profile rod frames should also be grounded separately.) The ComProtect earth bar features one contact guide for each pair; when the ComProtect protection plug is inserted into the module, its mating groove makes contact with the guide. This patented technology ensures optimum functionality and safety. The conductive contact between the protection plug s earth clip (earth contact of the protective circuit) and the earth bar is ensured during installation. In the LSA PROFIL system, additional earth clips must be installed in order to ensure a conductive contact (earth contact) between the earth bar and the profile mounting rods. Magazines for LSA-PLUS, LSA PROFIL and Main Distribution Frames (MDF 71) ADC KRONE s product portfolio includes various magazines for overvoltage protection. In addition to LSA-PLUS and LSA PROFIL distribution systems, magazines are available for MDF 71 and other related installations (drop wire and PCB modules). Various magazines are available for protection in the MDF 71 system. Typical three-point protection is implemented in the magazines; the protective components are connected to a common central connection (earth potential) when installed in the magazine. Overvoltage arrestors serve as protective components. They offer high energy absorption and very low capacitance values. In special cases, magazines can also be fitted with polycrystalline overvoltage protection components. Magazines can be particularly improved by installing fail-safe contacts in addition to the overvoltage arrestors. In the case of magazines for overvoltage protection in the LSA-PLUS distribution system, fail-safe contacts (thermal protection springs) can be simply plugged in, hence connecting them parallel to the two-electrode arrestors, or are just integrated onto the three-pole arrestors. If the arrestor overheats as a result of overvoltage, a solder material melts, triggering the fail-safe function to generate a short-circuit to earth parallel to the arrestors, hence discharging any subsequent currents. The same effect is achieved in other magazines (71/4 and 71/5) by installing fail-safe rings that close when the arrestors overheat, melting a prestressed fail-safe contact. w w w. a d c k r o n e. c o m ( 0 )

15 Technical Reference System Overview Three-electrode arrestors with optional fail-safe contacts are available for LSA-PLUS, LSA PROFIL and MDF 71 magazines. After the distribution system has been installed, all connection work is then carried out. Only when a low-resistance connection between rack frame and central earth bar and/or earth rod is established does the distribution frame provide an earth potential for the overvoltage protection components. The magazines are already equipped with earth contacts that, when installed, ensure a low-resistance path between rack frame and protection components. After the overvoltage arrestors and optional fail-safe contacts have been fitted, the magazines are inserted into the distributor module. Magazines for the MDF 71 (71/4 and 71/5) are inserted into the appropriate lateral contact insert (subscriber side) of the distributor element of the MDF 71.
