2 The underestimated risk Damage from surge voltages Those who consider damage from surge voltages to be caused only by direct lightning strikes with spectacular destruction forget that lightning strikes at distances of up to two kilometres can also cause devastating damage to electronic devices and s. And even everyday switching operations in the power network, e.g. through major s, can trigger dangerous surge voltages in the power network. Causes of damage Direct lightning strike Direct lightning strikes hit buildings with maximum destructive energy. Around 0% of lightning strikes involve between 0,000 and 00,000 A and can generate surge voltages of several 00,000 V. Remote lightning strike It is not only direct lightning strikes into a building that are dangerous, but also the more frequent strikes into the surrounding area of buildings. Here, brief voltage increases of millionths of seconds can occur A 0% of lightning strikes involve between 0,000 and 00,000 A More than 0,000 incidents of damage are reported to insurance companies each year.,00,000,000 More than. billion lightning strikes discharge each year worldwide.,000 In a radius of,000 metres, 0 to 0 close lightning strikes generate a dangerous surge voltage. 00 More than 00 lightning strikes discharge each second worldwide. Switching operations Switching operations such as switch-on and switchoff operations, the switching of inductive and capacitive loads and the interruption of short-circuit currents generate high surge voltages. Particularly when production plants, lighting s or transformers are switched off, electrical equipment located in close proximity can be damaged. % % of all electronic damage is caused by direct or indirect lightning strikes. Lightning strike and spread of the surge voltage

3 Worth protecting Surge protection required Modern electrical installation creates ever greater requirements for comfort and communication. The increasing number of devices also increases the risk of surge voltage damage on all devices, operated via the power, telephone or data network. Dangerous surge voltages also occur in pure via earth cables, as these cables cannot provide any significant reduction in potential differences. The installation of surge protection devices can guarantee a voltage limitation according to the insulation coordination. This avoids dangerous spark formation through short-circuits and, of course, the resulting fires. OBO lightning and surge protection s: Our comprehensive product range can offer you all-round protection. 00 V Dangerous voltages over,00 V Devices such as TV s, PCs or heating and building control s can survive brief surge voltages of up to,00 V. Lightning impacts or switching operations can, however, quickly exceed this voltage value by a multiple of times. OBO surge protection devices limit the voltage to considerably below,00 V. > 0,000 Damage to the building control, heating and air-conditioning technology. > 0,000 Subsequent damage: Failure of the entire building control, heating, lighting, security s and risk of fire. >,00 V Protected Up to km... beyond price Injury to people or irreparable data loss. Conclusion: Surge protection secures the function and comfort of the.

4 Surge protection - obligatory From 0, surge protection in all new buildings and in electrical installations will be mandatory for electrical installations conforming with the standard. The new standards HD 0-- and IEC 0-- describe the decision criteria as to when and how surge protection measures are required in s and buildings. Surge protection has been obligatory since 0. The new standard finally matches the increased requirements in the field of electrics and electronics..... The new HD 0-- and IEC 0-- The erection of surge voltage protection devices will now be obligatory for a standard electrical installation, if the influences of the surge voltages have an influence on: Human lives, e.g. s for safety purposes, medical areas. Public buildings and cultural facilities, e.g. failure of public services, telecommunications centres, museums. Commercial or industrial activities, e.g. hotels, banks, industrial companies, shops, agricultural operations. Groups of people, e.g. large housing blocks, offices, schools, churches. Resources in surge voltage category I + II are, for example, computers, heating s, building s or sensitive kitchen appliances. Installation location To arrest surge voltages before the electronic installation, surge voltage protection devices at the building entry must be used as a part of the equipotential bonding. The surge voltage devices should be installed as close to the source of interference as possible as protection against switching surge voltages. In the case of buildings with an external lightning protection or in the case of via an exposed cable, a type surge arrester must also be used. Protection area OBO surge protection devices limit the voltage at the installation location and also in feed lines between the main and subs of up to 0 m to a harmless 00 V. For cables longer than 0 m, inductive couplings can generate voltage peaks of a multiple of 00 V. These mean that additional surge protection devices are necessary on the electrical device to be protected. Protection circuit Feed lines from outside can couple in dangerous surge voltages. For this reason, it is necessary to protect all cables being run in from outside with surge protection devices. This creates a protection circuit with just one potential. REMARK: By influences on Individual people, e.g. in housing and small offices, surge protection is recommend. But, if the total economic value of the electronic installation to be protected is more than times the economic value of the SPD located at the origin of the installation, the using of SPD protection is necessary. Data and measurement and control cables Telecommunikations External lighting In accordance with these criteria, surge protection must be installed in all new buildings/s to ensure a standardised electrical installation. The new standard makes it obligatory The planner, the tradespeople and the owner and operator of a building are responsible for the correct planning and installation. Good to know: The new standard means that planners and the electrical installation engineers have a duty to inform the owner/operator. Failure to do so or undocumented information can lead to claims for regress by clients.
