16. Ungayibala kanjani i-generator yesigaba sesithathu yamanje?
Impendulo: I = P / (√3 Ucos φ) okungukuthi, yamanje = amandla (watts) / (√3 * 400 (volt) * 0.8).
Ifomula elenziwe lula ithi: I (A) = amandla alinganiswe ngamayunithi (KW) * 1.8
17. Buyini ubudlelwane phakathi kwamandla abonakalayo, amandla asebenzayo, amandla alinganisiwe, amandla amakhulu namandla wezomnotho?
Impendulo: 1) Iyunithi yamandla abonakalayo yi-KVA, esetshenziselwa ukuveza amandla wabaguquli ne-UPS ezweni lethu.
2) Amandla asebenzayo ayizikhathi ezingama-0.8 amandla abonakalayo, ku-KW, asetshenziswa kwimishini yokukhiqiza ugesi nemishini kagesi ezweni lami.
3) Amandla alinganisiwe esethi ye-diesel generator isho amandla angasetshenziswa ngokuqhubekayo amahora ayi-12.
I-4) Amandla amakhulu izikhathi ezi-1.1 zamandla alinganisiwe, kepha ihora elilodwa kuphela livunyelwe kungakapheli amahora ayi-12.
5) Amandla wezomnotho aphindwe ka-0.75 amandla alinganisiwe, okungamandla okukhipha okusethwe yi-generator kadizili angasebenza isikhathi eside ngaphandle komkhawulo wesikhathi. Lapho kusebenza la mandla, uphethiloli mncane futhi izinga lokwehluleka liphansi kakhulu.
18. Kungani kungavunyelwe ukuthi amasethi ediziliyeli asebenze isikhathi eside lapho amandla engaphansi kuka-50% wamandla alinganisiwe.
Impendulo: Ukwanda kokusetshenziswa kukawoyela kwenza izinjini zikadizili zithambekele ekwakhekeni kwekhabhoni, okwandisa izinga lokwehluleka futhi kunciphise isikhathi sokulungiswa.
19. Amandla wokukhipha wangempela we-generator ngesikhathi sokusebenza asuselwa ku-wattmeter noma ku-ammeter?
Impendulo: I-ammeter izobusa, futhi imitha yamandla ingeyenkomba kuphela.
20. Imvamisa namandla kagesi esethi ye-generator zombili azizinzile. Ngabe inkinga yinjini noma i-generator?
Impendulo: Ilele enjinini.
