2. Lightning arrester - Wikipedia

   en.wikipedia.org/wiki/Lightning_arrester

   Powerline worker performs maintenance of a lightning arrester on an electrical transmission tower in New Brunswick, Canada. A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and ...

3. Lightning rod - Wikipedia

   en.wikipedia.org/wiki/Lightning_rod

   A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...

4. Single-wire earth return - Wikipedia

   en.wikipedia.org/wiki/Single-wire_earth_return

   Each service site needs a rewirable drop out fuse for protection and switching of the transformer. The transformer secondary should also be protected by a standard high-rupture capacity (HRC) fuse or low voltage circuit breaker. A surge arrestor (spark gap) on the high voltage side is common, especially in lightning-prone areas.

5. Utility pole - Wikipedia

   en.wikipedia.org/wiki/Utility_pole

   [3] [4] It provides similar protection in case of flashovers and lightning strikes. A surge arrester (also called a lightning arrester) may also be installed between the line (ahead of the cutout) and the ground wire for lightning protection. The purpose of the device is to conduct extremely high voltages present on the line directly to ground.

6. Lightning strike - Wikipedia

   en.wikipedia.org/wiki/Lightning_strike

   A lightning rod or "Franklin rod" in honor of its famous inventor, Benjamin Franklin, is simply a metal rod, and without being connected to the lightning protection system, as was sometimes the case in the past, will provide no added protection to a structure. Other names include "lightning conductor", "arrester", and "discharger"; however ...

7. Shunt (electrical) - Wikipedia

   en.wikipedia.org/wiki/Shunt_(electrical)

   However, a direct lightning strike (such as on a radio tower antenna) will cause the shunt to arc and conduct the massive amount of electricity to ground, protecting transmitters and other equipment. Another older form of lightning arrester employs a simple narrow spark gap, over which an arc will jump when a high voltage is present.

   Dominic Zvada kicked a 21-yard field goal with 45 seconds left and Michigan stunned No. 2 Ohio State 13-10 on Saturday, ending the Buckeyes ’ hopes of returning to the Big Ten title game. Kalel ...

9. Insulator (electricity) - Wikipedia

   en.wikipedia.org/wiki/Insulator_(electricity)

   Arcing horns and lightning arresters are necessary because lightning strikes to the mast are common. Guy wires supporting antenna masts usually have strain insulators inserted in the cable run, to keep the high voltages on the antenna from short circuiting to ground or creating a shock hazard.
