Ha ho bapisoa le li-transformer tsa khale, li-pad-li-transformer tse kentsoeng ho bonolo ho li kenya, 'me tlhokomelo ea kamehla le tlhahlobo e batla e le bonolo, e leng ho etsang hore ho be bonolo ho kenya likarolo tse senyehileng kapele. Hangata ba sebelisa oli-e pholileng e qoelisoang, moo phepelo ea tlhaho ea oli ea transformer e felisang mocheso. Li-transformer{{9}tse palamisitsoeng li entsoe ka matla a ho tloha ho 15 kVA ho isa ho 5000 kVA. Hangata li na le li-fuse tse kopantsoeng le li-switches bakeng sa polokeho le ts'ebetso e ntlafetseng. Lithapo tsa motlakase tse ka sehloohong li ka hokeloa ho sebelisoa lihokelo tsa setsoe, tse sebetsang ha transformer e ntse e matlafatsoa ka thupa e chesang. Setupo sena se fana ka maemo a bonolo ha ho lokisoa le ho lokisoa, ho lumella lits'ebeletso tse bonolo le tse sebetsang hantle.

1.2 Maemo a Tšebeletso

Thepa e tla kenngoa ka ntle tikolohong e haufi le lebōpo la tropike e nang le lehalima le matla, mongobo o phahameng, le maholiotsoana ka linako tse ling. Sebaka sa tikoloho se letsoai ebile sea chesa.

Maemo a kakaretso a litšebeletso:
a. Bophahamo: <1,524 m (5,000 ft)
b. Mongobo o amanang (karolelano ea selemo): 80%
c. Bonyane mocheso: 4.4 degrees
d. Boholo ba mocheso: 40 degrees
e. Boholo ba mocheso oa lihora tse 24: likhato tse 30
f. Mocheso o tloaelehileng oa selemo: likhato tse 26
g. Sebaka sa ho kenya: Ka hare ho 30 m ho tloha leoatleng
