Data networks companies or emergency facilities such hospitals and fire stations are lifelines for essential real time information ex- change. Overview current standards: • Internal lightning protection IEC 62305-4 • Surge protection IEC 60364-5-53 Surge protection devices increase the availability electronic systems. Like bird a high tension line, the electrical device raised a single potential and thus protected. the Directive VDS 2010 (German guideline the insurance association). Surge protection devices (SPDs) are, like an open switch, connected the equipotential bond- ing and safely short circuit the surge voltage before a destructive failure the insulation. Ever more frequently, today's elec- tronic devices are damaged surge voltages caused by remote lightning discharges switching opera- tions large electrical systems. This destroys the device. Internal lightning protection systems and surge voltage protection concepts are covered current standards and meet the very latest requirements. It's surprise, then, that prop- erty insurers are checking more and more claims and stipulating the use devices protect against surges. banks media publishers, need reliable transmission paths. It not only lightning strikes that pose latent threat to these systems.g. These voltage peaks can penetrate building though all manner conductive connections and cause enormous damage.The internal lightning protection system Our dependency electrical and electronic equip- ment continues increase, both our profession- al and private lives. During thunderstorms too, high volumes energy are instantaneously released. Current statistics and estimates insurance compan- ies show: damage levels caused surges exclud- ing consequential outage costs long since reached drastic levels due the growing dependency on electronic devices. Surge protection through equipotential bonding If electrical devices are subjected high potential difference surge voltage, then the insulation the voltage resistance may exceeded. Information protection measures can be found e
