- Definition(s)
- A device that connects to and protects an electrical system from lightning and other voltage surges. DIY Doctor
- Example sentence(s)
- Lightning arresters are installed on many different pieces of equipment such as power poles and towers, power transformers, circuit breakers, bus structures, and steel superstructures in substations. - United States Department of Labor by
- The present invention relates to a lightning arrester comprising resistance elements made of zinc oxide as a main component, having a nonlinear voltage-current characteristic and being disposed in an insulating cylinder... - Free Patents Online by
- This reduction in resistance continues until the lightning arrester acts just like a direct short to ground. Upon reaching this condition, the lightning energy diverts to ground away from the protected equipment, thus reducing the effect of the overvoltage. - EC&M by

- Parafoudre
Un parafoudre (ou parasurtenseur) est un dispositif de protection des appareillages électriques ou électronique contre les surtensions électriques transitoires générées par exemple par la foudre ou certains équipements industriels. Wikipedia - by FX Fraipont (X)
- Example sentence(s)
- La réglementation en vigueur recommande et impose même, dans certains cas, la pose d'un parafoudre. C'est pourquoi Hager édite son guide technique des parafoudres pour s'adapter aux nouvelles exigences de la norme NFC 15-100 (mise à jour en août 2005) et du guide technique UTE C15-443 (modifié en août 2004). - Hager by FX Fraipont (X)
- Quel que soit le type de parafoudre, le principe reste le même. Le parafoudre se comporte un peu comme un interrupteur, qui au-delà d'un principe du parafoudre de type éclateurcertain seuil de tension va laisser s'échapper le courant électrique vers la terre, et ainsi éviter qu'il ne se fraye son propre chemin au sein des différents appareils raccordés au réseau électrique. - Entraidelec by FX Fraipont (X)

- Definition(s)
- apparecchio di protezione degli impianti elettrici contro le sovratensioni di origine atmosferica, che scarica a terra. Dizionario Garzanti - by Michele Armellini
- Example sentence(s)
- SCARICATORE DI SOVRATENSIONE DI ORIGINE ATMOSFERICA: dispositivo destinato a proteggere le apparecchiature della stazione elettrica dalle sovratensioni,ovvero dall’anormale innalzamento della tensione verso terra e/o tra le fasi rispetto al valore normale di funzionamento. Possono avere origine sulle linee elettriche in seguito a perturbazioni atmosferiche (fulminazione diretta/indiretta), oppure sulla linea stessa a causa di errate manovre.
Sono collegati all’arrivo delle linee su ciascuna fase a monte del trasformatore. - Studio di fattibilità di un nuovo stall by Michele Armellini
- Curva caratteristica della tensione di rete in caso di
intervento di uno scaricatore per corrente da fulmine - Protezione dalle Sovratensioni by Michele Armellini
- Gli scaricatori e i limitatori di
sovratensione sono realizzati
con diverse tecniche costruttive,
tuttavia è possibile chiamarli in
modo generico SPD. - Scaricatori e limitatori di sovratension by Michele Armellini

- Definition(s)
- Bleskojistka je ochranný prvek, který se zpravidla připojuje mezi vodič připojený k chráněnému zařízení a uzemnění. Dojde-li na tomto vodiči k přepětí (např. při bouřce), bleskojistka se zapálí a odvede přepětí do země. Mutenice - by Dalibor Uhlik
- Example sentence(s)
- Žádná běžná bleskojistka sice není úplně stoprocentní, ale při vhodné volbě je obvykle možné následky poškození podstatně snížit a tím zlevnit následnou opravu.
- Fonservis by Dalibor Uhlik
