Ma Surge nthawi zambiri samayang'aniridwa. Kutulutsa kwamagetsi kwamagetsi (komwe kumangotenga mphindi zochepa) kumachitika chifukwa cha kuwombera kwachindunji, kwapafupi komanso kwakutali kwa magetsi kapena kusintha kwa magetsi.

Kuwongolera mphezi zapafupi ndikuwomba mphezi munyumba, pafupi kwambiri kapena m'mizere yolowera mnyumbayo (mwachitsanzo, mphamvu yamagetsi yamagetsi, kulumikizana kwamafoni, ndi mizere ya ma data). Matalikidwe ndi mphamvu zamagetsi zomwe zimayambitsidwa ndimomwe zimakhalira komanso ma voltages komanso gawo lamagetsi lamagetsi (LEMP) lomwe likuwopseza dongosolo kuti litetezedwe.

Mphezi yomwe imabwera chifukwa cha mphezi yolowera munyumba imapangitsa kuti pakhale ma volts angapo 100,000 pazida zonse zoumbidwa. Zowonjezera zimayambitsidwa chifukwa chakuchepa kwamagetsi pamagetsi abwinobwino padziko lapansi komanso kutuluka kwanyumbayo pokhudzana ndi chilengedwe. Izi ndizopanikiza kwambiri pamagetsi amnyumba.

Kuphatikiza pa kutsika kwamagetsi pamiyeso yofananira ndi ma earthing, ma surges amapezeka pakukhazikitsa magetsi mnyumbayo ndi machitidwe ake olumikizidwa chifukwa champhamvu yolowetsa mphezi yamagetsi yamagetsi. Mphamvu za ma surges omwe amachititsa kuti mafunde azitha kuyenda pang'ono amakhala otsika poyerekeza ndi momwe mphezi zimayendera pakali pano.

Mphezi zakutali ndizowomba mphezi kutali ndi chinthu chomwe chiyenera kutetezedwa, mumtambo wapakatikati wamagetsi kapena pafupi kwambiri komanso kutulutsa kwamtambo mpaka mtambo.

Kusintha magwiritsidwe azinthu zamagetsi kumayambitsa ma surges (SEMP - switching Electromagnetic Pulse) ya ma volts 1,000 m'magetsi. Zimachitika, mwachitsanzo, zinthu zikuluzikulu (monga ma transformer, ma reactor, ma motors) zimazimitsidwa, ma arcs amayatsidwa kapena kusokoneza ulendo. Ngati magetsi ndi mizere ya data imayikidwa mofananamo, makina azovuta amatha kusokonezedwa kapena kuwonongedwa.

Makina owonongeka m'nyumba zanyumba, maofesi ndi oyang'anira ndi mafakitale atha kuchitika, mwachitsanzo, magetsi, makina azidziwitso ndi mafoni, njira zowongolera zopangira kudzera ku Fieldbus komanso owongolera ma air-condition kapena magetsi . Machitidwe ofunikirawa amatha kutetezedwa ndi lingaliro lathunthu loteteza. Poterepa, kugwiritsidwa ntchito kwa zida zodzitchinjiriza (mphezi pano ndi omanga mafunde) ndikofunikira kwambiri.

Ntchito ya mphezi zomwe zimamangirira pano ndikupanga mphamvu zazikulu popanda chiwonongeko. Amaikidwa pafupi kwambiri mpaka pomwe magetsi amalowa mnyumbamo. Surge arresters, nawonso, amateteza zida za terminal. Amayikidwa pafupi kwambiri momwe zingatetezedwe.

Ndi banja lake lazogulitsa zamagetsi zamagetsi ndi ma data, LSP imapereka zida zogwirizira zotetezera. Zojambulazo zimalola kukhathamiritsa kosakwanira kwamalingaliro achitetezo amitundu yonse yazomanga ndi kukula kwake.
