Mbiri ya chitetezo cha mphezi inayamba m'ma 1700, koma pakhala kupita patsogolo kochepa pa ukadaulo. Preventor 2005 inapereka njira yoyamba yatsopano mumakampani oteteza mphezi kuyambira pomwe idayamba m'ma 1700. Ndipotu, ngakhale masiku ano, zinthu zomwe zimaperekedwa nthawi zambiri zimakhala ndodo zazing'ono zachikhalidwe zolumikizidwa ndi waya wowonekera - ukadaulo womwe unayamba m'ma 1800.

1749 - Ndodo ya Franklin.Kupeza momwe magetsi amayendera kumatikumbutsa chithunzi cha Benjamin Franklin ataima mumphepo yamkuntho akugwira mbali imodzi ya kite ndipo akuyembekezera kuti mphezi imugwere. Pa "kuyesera kwake kupeza mphezi kuchokera ku mitambo ndi ndodo yolunjika," Franklin adasankhidwa kukhala membala wovomerezeka wa Royal Society mu 1753.Kwa zaka zambiri, chitetezo chonse cha mphezi chinali ndi Franklin Rod yopangidwa kuti ikope mphezi ndikuyiponya pansi. Inali ndi mphamvu zochepa ndipo masiku ano imaonedwa kuti ndi yakale. Tsopano njira iyi nthawi zambiri imaonedwa kuti ndi yokwanira pa zipilala za tchalitchi, ma chimney ataliatali ndi nsanja zomwe madera otetezedwa ali mkati mwa cone.

1836 - Dongosolo la Khola la Faraday.Kusintha koyamba kwa ndodo ya mphezi kunali khola la Faraday. Ili kwenikweni ndi khola lopangidwa ndi ukonde wa zinthu zoyendetsera padenga la nyumba. Dzina lake lochokera kwa wasayansi waku England Michael Faraday, yemwe adazipanga mu 1836, njira iyi si yokhutiritsa kwenikweni chifukwa imasiya malo pakati pa denga pakati pa ma conductor osatetezedwa, pokhapokha ngati atetezedwa ndi malo opumira mpweya kapena ma conductor a denga pamlingo wapamwamba.

• Pa Faraday System, chitetezo cha mphezi chimapangidwa ndi ndodo zingapo za mphezi, zosachepera phazi limodzi, zokhazikika pamalo onse oonekera padenga. Ziyenera kulumikizidwa pamodzi ndi ma conductor a padenga ndi ma conductor ambiri otsikira pansi kuti apange khola losapitirira mapazi 50 x mapazi 150 ndipo zikhale ndi malo opumira mpweya pamalo olumikizirana denga lapakati.
  Nyumba yomwe ikuimiridwa pano ndi 150 ft. x 150 ft. x 100 ft. kutalika. Njira ya Faraday ndiyokwera mtengo kuyiyika, imafuna zida zambiri padenga komanso malo olowera denga kangapo ... koma mpaka pakati pa zaka za m'ma 1900, panalibe china chabwino kuposa ichi.

• 1953 - Woteteza.Choteteza ndi malo opumira mpweya omwe amayatsa ma ioni omwe amagwira ntchito mwachangu. JB Szillard anayamba kuyesa makina owunikira ma ioni ku France, ndipo mu 1931, Gustav Capart adapatsa chilolezo chotere. Mu 1953, mwana wa Gustav Alphonse adasintha chipangizo cha abambo ake, ndipo kupanga kwake kunabweretsa chomwe tikudziwa lero kuti Choteteza.
  Pambuyo pake, Preventor 2005 inakonzedwanso ndi a Heary Brothers a ku Springville, New York.
  Zoletsa zimagwira ntchito mosinthasintha, pomwe njira zakale sizimasinthasintha. Mwachitsanzo, pamene mtambo wamkuntho ukuyandikira nyumba yotetezedwa, mphamvu yamagetsi ya ma ion pakati pa mtambo ndi nthaka imawonjezeka. Ma ion omwe amayenda nthawi zonse kuchokera mu chipangizocho, amanyamula mphamvu zina za ma ion pansi kupita ku mtambo, ndipo izi zimapangitsa kuti mphamvu ya ion pakati pa mtambo ndi nthaka ichepe kwakanthawi. Tiyenera kumvetsetsa bwino kuti sizingathetse mtambo. Sizimangochepetsa mphamvu ya ion kwa kanthawi kochepa komwe mtambo umadutsa pamwamba - koma kuchepetsa kwakanthawi kwa mphamvu nthawi zina kumakhala kokwanira kuteteza kutuluka kwa mphezi kuti kusayambitse. Kumbali ina, pamene kuchepetsa mphamvu kumeneku sikukwanira kuletsa kuyambitsa, ion streamer yoyendetsa bwino imaperekedwa kuti iyendetse kutuluka kwa ion mosamala kupita ku dziko lapansi/pansi.
  Heary Brothers yakhala ikugwira ntchito kuyambira mu 1895 ndipo ndi kampani yayikulu komanso yakale kwambiri yopanga zida zoteteza mphezi padziko lonse lapansi. Sikuti imangopanga Preventor yokha, komanso imatsimikizira kuti ikugwira ntchito bwino. Chitsimikizochi chimathandizidwa ndi kampani yainshuwalansi ya zinthu ya madola mamiliyoni khumi.
