A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external lightning or internal events. Also called a surge protection device or transient voltage surge suppressor  this class of device is used to protect equipment power transmission and distribution systems.

Surge arresters are not generally designed to protect light against a direct lightning strike to a conductor, but rather against electrical deflection resulting from lightning strikes occurring in the vicinity of the conductor. Lightning which strikes the earth results in ground currents which can pass over buried conductors and induce a transient that propagates outward towards the ends of electric conductor. The same kind of induction happens in overhead and above ground conductors which experience the passing energy of an atmospheric EMP caused by the lightening strike. Surge arresters only protect against induced transients characteristic of a lightning discharge's rapid rise-time and will not protect against electrification caused by a direct strike to the conductor. Transients similar to entry of light, such as from a high voltage system's fault switching, may also be safely diverted to ground; however, continuous over currents are not protected against by these devices. The energy in a handled transient is substantially less than that of a lightning discharge; however it is still of sufficient quantity to cause equipment damage and often requires protection.

A lightning arrester may have a block of a semiconducting material such as silicon carbide  was once a trade name for the silicon carbide used in arresters. Some spark gaps are open to the air, but most modern varieties are filled with a precision gas mixture, and have a small amount of radioactive material to encourage the gas to ionize when the voltage across the gap reaches a specified level. Other designs of lightning arresters use a glow-discharge tube connected between the protected conductor and ground

Moreover, the choice of materials used in the making of Siemens surge arresters contributes to the protection of the environment.

Hubbell Power Systems arresters are gapless and consist of a column of metal-oxide blocks connected between main and Earth. The blocks can withstand a significant power frequency overvoltage for a limited time, depending on the magnitude of any immediately preceding surge duty. This duty can be the result of switching surges on higher voltage lines, or from other sources. The temporary overvoltage capability can be determined from the TOV curve. The prior duty curve is based upon absorption of rated energy immediately preceding application of the overvoltage.

A lightning protection system is intended to safeguard a structure from injury thanks to lightning strikes by intercepting such strikes and safely passing their extraordinarily high currents to ground. A lightning protection system includes a network of air terminals designed to produce an occasional ohmic resistance path to ground for potential strikes.

Lightning protection systems square measure accustomed stop or reduce lightning strike injury to structures. Lightning protection systems mitigate the hearth hazard that lightning strikes cause to structures. A low-impedance protection system square measure provided by lightning protection for lightning current to minimize the heating impact of current flowing through ignitable structural materials. If lightning travels through porous and water-saturated materials, these materials could virtually explode if their water content is flashed to steam by heat made from the high current. Usually this can be why trees square measure often shattered by lightning strikes.

Because of the high energy and current levels associated with lightning currents is in additional than 100 and fifty amps, and additionally the very speedy rise time of a lightning strike, no safety method can guarantee absolute safety from lightning. These current will divide to follow every semi semiconducting path to ground, and even the divided current can cause hurt. Secondary side-flashes is enough to ignite a fireplace, blow apart brick, stone, or concrete, or injure occupants at intervals a structure or building. However, the benefits of basic lightning protection systems square measure evident for overflow a century.

Laboratory-scale measurements of the results of [any lightning investigation research] don\'t scale to applications involving natural lightning. Field applications have primarily been derived from trial and error supported the most effective supposed laboratory analysis of a extremely advanced and variable phenomena.
