Amasistimu kagesi abucayi kakhulu atholakala ezakhiweni nasezinhlelweni zesitimela eziningi, kufaka phakathi, kepha kungagcini ngokusayina nokulawula amasistimu:

• Ukuxhumeka kwe-elekthronikhi
• Izinhlelo zokubonisa ezibonakalayo
• Izinhlelo zokuwela ezingeni lokuwela

Izakhiwo, amasistimu, kanye nemishini ye-elekthronikhi ehambisanayo, noma kunjalo, zisengozini yeziteleka zombani kanye neminye imithombo yokuphazamiseka ngogesi. Ukulimala kubangelwa zombili iziteleka eziqondile zombane (ngokwesibonelo, kolayini abaphezulu, amathrekhi noma izinsimbi) kanye neziteleka zombani ezingaqondile (ngokwesibonelo, esakhiweni esihlangene). Iziteleka zombani ezingaqondile zibangela ama-surge akhuphukile nemisinga yombani engakhethi.

Ngaphezu kwalokho, kufanele kubhekwe ama-surges abangelwa ngaphakathi kohlelo lwesitimela. Kulo mongo, kwenziwa umehluko phakathi kokushintsha ama-overvoltages (imvamisa ebangeni le-microsecond) nokuvuthwa kwesikhashana. Lokhu kuqubuka kwesikhashana kungahlala imizuzwana eminingana noma ngisho nemizuzu kuze kube yilapho uhlelo lwesitimela lunqanyuliwe kumadivayisi okuvikela wesitimela.

Ezimweni eziningi, abaqhubi abalimele noma ababhujisiwe, izinto ezixhumanayo, amamojula noma izinhlelo zamakhompiyutha ziholela ekuphazanyisweni kokusebenza kwezitimela nasendaweni enamaphutha edla isikhathi. Ngenxa yalokhu, izitimela ziyabambezeleka futhi kubiza izindleko eziphezulu. Ngalezi zizathu, umqondo ongaguquguquki wombani nokuvikelwa kokuqhuma ohambisana nohlelo olufanele kubandakanya ukuvikelwa kombani wangaphandle nezindlela zokubopha i-equipotential kuyadingeka. Ngakho-ke, isikhathi sokuphumula kanye nokuphazamiseka okubizayo komsebenzi wesitimela kungancishiswa kube okungenani.

Ngenxa yesipiliyoni sayo ekuvikeleni kombani nokuqhuma emashumini eminyaka kanye nocwaningo olunzulu ngezinhlelo zokuhlinzeka ngogesi wesitimela, i-LSP inikeza imiqondo ephelele yokuvikela ngezixazululo eziphelele nemikhiqizo emisha. Iphothifoliyo yemishini yokuphepha ebanzi ishiya uhla lwemikhiqizo.
