Power Systems Substation Automation. Upvote 1 Views Followers 2. Write an Answer Register now or log in to answer. Transmission Line Lightning Protection: The transmission line towers would normally be higher than a substation structure, unless you have a multi-storey structure at your substation.

Earth Mats are essential in all substation areas, along with driven earth electrodes unless in a dry sandy desert site. It is likewise normal to run catenaries aerial earth conductors for at least1kM out from all substation structures.

Those earth wires to be properly isolated electrically to each supporting transmission tower, and bonded back to the substation earth system. It is important to have the catenary earth conductors above the power conductor lines, at a sufficient distance and position that a lightning strike will not hit the power conductors.

In some cases it is thus an advantage to have two catenary earth conductors, one each side of the transmission tower as they protect the power lines below in a better manner. In lightning-prone areas it is often necessary to have catenary earthing along the full distance of the transmission line. In some older outdoor substation structures, air-break isolator switches are often at a very high point in the structure, and in those cases small structure extension towers are installed, with electrodes at the tapered peak of those extension towers.

The extension towers are normallymm square approximately until the extension tower changes shape at the tapered peak, and in some cases project upwards from the general structure2 to6 metres, with the electrode some2 to3 metres projecting upwards from the top of the extension tower.

The Difference Between a Lightning Arrester & Surge Arrester

State the difference between Surge Arrester and Lightning arrester,Both are same or not? Surge Arresters are widely also known Lightning arresters. However strictly speaking the two are in fact different. However Lightning arresters are separate instruments specifically designed for protection of structures solely from lightning this equipment neutralizes the charge by nullifying the charge it receives from the lightning and grounds it. The main differences between a lightning arrester and a surge arrester are time and position.

Surge arrester protects the system from lightning, switching, electrical faults and other transients voltage and surges while lightning arrester are mainly used for lightning strikes and associated surges. Surge arrester can be used as a lighting arrester while lighting arrester can't be used as a surge arrester.

Surge Arresters: fundamentals of surge arresters

Surge arresters are voltage limiting devices used to protect electrical insulation from voltage spikes in a power system. Similar to how a fuse functions to protect an electrical system from damage due to overcurrent conditions, the job of a surge arrester is to protect the system from damage due to overvoltage conditions. In the past surge arresters were called lightning arresters, this name was based on their primary objective of protecting electrical insulation from lightning strikes on the system.

A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. It prevents continued flow to follow current to ground and it is capable of repeating these functions as specified per ANSI standard C An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage and protects the equipment installed in parallel. Surge arresters have many applications, anywhere from protecting a home to a utility substation.

A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external lightning or internal switching events. Also called a surge protection device SPD or transient voltage surge suppressor TVSS , this class of device is used to protect equipment in power transmission and distribution systems. For consumer equipment protection, different products called surge protectors are used.

Он заберет личные вещи Танкадо и вернется домой. Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах.

 Вы из полиции. Беккер покачал головой. Панк пристально смотрел на. - Вы похожи на полицейского.

What is the difference between Surge Arrester & Lightning Arrester?

Потом закрыл глаза и глубоко вздохнул. Беккер не сразу почувствовал, что его кто-то подталкивает. Подняв глаза, он увидел старика с усыпанным родинками лицом, который стоял перед ним, намереваясь пройти. Беккера охватила паника. Он уже хочет уйти.

Кольцо словно исчезло у него из-под носа. Это совсем не обрадует коммандера Стратмора. Клушар приложил руку ко лбу. Очевидно, волнение отняло у него все силы. Его лицо залила мертвенная бледность.

 Я сделал это ради нас обоих. Мы созданы друг для друга. Сьюзан, я люблю.  - Слова лились потоком, словно ждали много лет, чтобы сорваться с его губ.

Предпоследний щит становился все тоньше.

Definition: The device which is used for the protection of the equipment at the substations against travelling waves, such type of device is called lightning arrester or surge diverter.
