Enkola za AC zikola bulungi ebitundu nga 2% ku 6% okusinga enkola za DC. Naye DC esobola okuba ennungi mu mbeera ezimu, nga ne Variable Speed Drives (VSD), nga eno ekola bulungi ebitundu nga 1%. Okumanya enjawulo zino kikuyamba okulonda enkola entuufu ku pulojekiti yo, ka kibeere waka oba mu mulimu.
Okukyusa watts mu amps mu nkola za DC, kozesa ensengekera eno:
Amps = Watts ÷ Volts
Enkola za DC zirina vvulovumenti etakyukakyuka, ekifuula okubala okwangu. Okugeza, singa ekyuma kikozesa watts 120 era nga kikola ku volts 12:
Amps = 120 ÷ 12 = 10
Ekyuma kino kyetaaga amps 10 okukola. Kino kikuyamba okuteekateeka circuit ezikwata current obulungi. Era ekuuma waya n’ebitundu obutatikka nnyo.
Obulung’amu kikulu mu nkola za DC. Kiraga engeri amaanyi agayingira gye gafuuka obulungi okufuluma okw’omugaso. Ensengekera eri nti:
Obulung’amu (%) = (Amaanyi agafuluma ÷ Amaanyi agayingira) × 100
Enkola ennungi zimala amaanyi matono ate nga zigula ssente ntono okuddukanya. Ebintu nga omutindo gw’ekitundu n’ebitwetoolodde bikosa obulungi. Okumanya bino kiyamba okulongoosa omulimu n’okukekkereza amaanyi.
Wano waliwo ebyokulabirako by’okukyusa watts okudda mu amps mu nkola za DC. Mota entono ekozesa watts 12 era ekola ku volts 12. Nga tukozesa ensengekera:
Amps = Watts ÷ Volts = 12 ÷ 12 = 1
Motor yeetaaga amp 1. Ekyuma ekinene kikozesa watts 24 era kikola ku volts 12. Okubala kuli:
Amps = 24 ÷ 12 = 2
Ekyuma kino kyetaaga 2 amps. Ebyokulabirako bino biraga engeri ensengekera gy’eyambamu okuzuula kasasiro eri ebyuma. Wano waliwo emmeeza ennyangu:
| Watts | Volts | Amps |
|---|---|---|
| 12 | 12 | 1 |
| 24 | 12 | 2 |
Okukozesa emitendera gino kikakasa nti circuits zisobola okukwata current mu ngeri ennungi. Okumanya kuno kuyamba okuzimba enkola ezikola obulungi n’okukekkereza amaanyi.
Single-phase AC circuits zikozesebwa mu maka n’amaduuka amatono. Zituusa amaanyi nga zirina amayengo ga vvulovumenti agamu agakyukakyuka. Okuzuula amps okuva mu watts mu circuit zino, kozesa ensengekera eno:
Amps = Watts ÷ (Volts × Power Factor) .
Ensonga y’amaanyi eraga engeri amasannyalaze gye gakozesebwamu obulungi. Kiva ku 0 okutuuka ku 1, nga 1 y’asinga. Okugeza, singa ekyuma kikozesa watts 1000, nga kikola ku volts 120, era nga n’amaanyi ga 0.8:

Kino kitegeeza nti ekyuma kino kyetaaga amps 10.42. Okumanya kino kikuyamba okulonda waya n’ebimenya ebitaliiko bulabe.
Single-phase circuits zikola bulungi ku byuma ebitonotono. Naye zifiirwa amaanyi mangi nga zirina ebyuma ebinene. Okutereeza vvulovumenti kiyinza okulongoosa engeri gye zikolamu. Okugeza, okutereeza ensobi n’okukendeeza ku kukyusakyusa kwa harmonic (THD) kizifuula ennungi. Wano waliwo emmeeza egeraageranya omulimu:
| Ekiraga omulimu Ensobi | y’omugugu ogutali gwa linnya Okulongoosa | ensobi y’omugugu ogutali gwa bbalansi | ne RL-TD3 Agent |
|---|---|---|---|
| Ensobi mu mbeera etali ya kukyukakyuka | Ebitundu 50% okusingawo | Okutuuka ku mirundi 5 okusingawo | Ennongoosereza ennene |
| Ensobi Ripple | Okutuuka ku bitundu 20% waggulu | Emirundi nga 4 okusingawo | Okulongoosa okweyoleka |
| Okukyusakyusa kwa Harmonic kwonna (THD) . | Omutindo omulungi | Yalongoosebwa ne RL-TD3 | Okufuga okunywezeddwa |
Nga tutereeza ensonga zino, circuit za phase emu zisobola okukola obulungi.
Amakolero g’amasannyalaze aga AC circuits eza phase ssatu n’ebizimbe ebinene. Zikozesa amayengo ga vvulovumenti asatu, nga buli limu lyawukana diguli 120. Dizayini eno efuula okutuusa amasannyalaze okubeera okunywevu era okukola obulungi. Okukyusa watts okudda mu amps mu circuit zino, kozesa ensengekera eno:
Amps = Watts ÷ (√3 × Volts × Power Factor) .
Okugeza, singa ekyuma kikozesa watts 5000, nga kikola ku volts 400, era nga n’amaanyi ga 0.9:
Amps = 5000 ÷ (√3 × 400 × 0.9) ≈ 8.03
Kino kitegeeza nti ekyuma kino kyetaaga amps nga 8.03. Circuit za phase ssatu zifiirwa amaanyi matono era zikwata bulungi ebyuma ebinene.
Circuit zino zitera okubeera mu makolero olw’ensonga nnyingi. Amakolero agasukka mu 90% gazikozesa okukola amasannyalaze amalungi. Era zifiirwa amaanyi matono ku lugendo oluwanvu. Plus, bakuleka okwongera ebyuma ebirala mu ngeri ennyangu. Wano waliwo emmeeza y'emigaso gyazo:
| obw'enkizo | Obujulizi |

Kebera emirundi ebiri ennamba zo naddala voltage ne power factor. Okukozesa yuniti enkyamu oba okuzingulula amangu kiyinza okuleeta ensobi. Buli mutendera guwandiike bulungi okulaba ensobi nga bukyali.
Calculator ya watts to amps eyamba enkola eno ennyangu era eyangu. Yingiza watts, volts, ne power factor (bwe kiba kyetaagisa) okufuna amps mu bwangu. Calculators nnyingi ez’obwereere zisangibwa ku mutimbagano. Ziyamba ku nkola za AC eza phase ssatu ezirimu obukodyo.
Emmeeza ezijuliziddwa nazo za mugaso. Bw’oba otera okukola ne vvulovumenti eza bulijjo nga 120V oba 230V, teeka emmeeza y’okukyusa okumpi. Kikekkereza obudde era kiyamba mu pulojekiti ezirimu ebyuma bingi.
Obukuumi bukulu nnyo ng’okola emirimu gy’amasannyalaze awaka. Nga tonnakyusa watts okudda mu amps, kebera ebyuma byo ebyetaago by’amasannyalaze. Kozesa sayizi ya waya entuufu ne circuit breaker okusinziira ku kubalirira kwo. Bw’oba tokakasa, saba omusawo w’amasannyalaze akuyambe. Basobola okukakasa nti setup yo egoberera amateeka g’obukuumi.
Totikka nnyo circuits. Gattako amaanyi g’ebyuma byonna ku circuit. Saasaanya omugugu mu circuits bwe kiba kyetaagisa. Kino kyewala ebbugumu erisukkiridde era kikendeeza ku bulabe bw’omuliro. Bulijjo kozesa ebintu eby’omutindo omulungi okusobola okufuna obukuumi obw’olubeerera.
Okukyusa watts okudda mu amps kyangu nga olina ekitabo ekikulaga amangu. Wansi waliwo ekipande ekiraga enkyukakyuka eza bulijjo ku nkola za 120V, 230V, ne 400V. Namba zino zitwala ensonga y’amaanyi eya 1 okusobola okubala okwangu.
| Watts | 120V (Amps) | 230V (Amps) | 400V (Amps) . |
|---|---|---|---|
| 100 | 0.83 | 0.43 | 0.25 |
| 500 | 4.17 | 2.17 | 1.25 |
| 1000 | 8.33 | 4.35 | 2.5 |
| 2000 | 16.67 | 8.7 | 5 |
| 5000 | 41.67 | 21.74 | 12.5 |
Omulongooti guno gulaga ebyuma bya kasasiro bwe byetaaga ku vvulovumenti ez’enjawulo. Okugeza, ekyuma kya watt 1000 ku nkola ya 230V kikozesa amps nga 4.35.
Emmeeza ya watts to amps ya mugaso mu kutegeka ensengeka z’awaka oba ez’amakolero. Awaka, kikuyamba okulonda waya n’ebimenya ebituufu eby’ebyuma nga microwave. Okugeza, microwave ya watt 1200 ku circuit ya 120V yeetaaga breaker ewagira waakiri amps 10.
Mu makolero, emmeeza eyamba okubala ebyuma ebinene. Motoka ya watt 5000 ku nkola ya 400V yeetaaga amps 12.5. Kino kikakasa nti waya zo n’ebimenya bisobola okukwata omugugu obulungi. Okukozesa emmeeza eno kikekkereza obudde era kiziyiza circuit ezitikkibwa ennyo.
Amagezi : Kebera amaanyi g’ekyuma kyo. Singa eba wansi wa 1, current ejja kuba waggulu. Teekateeka okubalirira kwo okusobola okusigala nga tolina bulabe.
Okumanya okukyusa watts okudda mu amps kikuyamba okukola n’amasannyalaze mu ngeri ey’obukuumi era mu ngeri ennyangu. Kati otegedde engeri watts, amps, ne volts gye zikwataganamu n’engeri y’okukozesaamu ensengekera z’enkola za DC ne AC. Emitendera gino giyamba okwewala circuit ezitikkibwa ennyo, okulonda ebitundu ebituufu, n’okukola setups ez’amaanyi.
Okumanya kuno kukozese mu pulojekiti zo okusigala nga tolina bulabe n’okukekkereza amaanyi. Ka obe ng’oteekawo amasannyalaze g’enjuba oba okulongoosa waya z’awaka, obukugu buno bukuyamba okusalawo mu ngeri ey’amagezi. Weegezeemu emirundi mingi okuwulira nga weesiga okuddukanya enkola z’amasannyalaze.
Kozesa ensengekera eno ennyangu:
Amps = Watts ÷ Volts
Ku nkola za AC , ssaako ensonga y’amaanyi:
Amps = Watts ÷ (Volts × Power Factor) .
Kino kikola ku circuit zombi eza phase emu n’eza phase ssatu. Bulijjo kebera vvulovumenti n’amaanyi g’ekyuma kyo okuzuula ebituufu.
Ensonga y’amaanyi eraga engeri amasannyalaze gye gakozesebwamu obulungi. Ensonga y’amaanyi entono kitegeeza nti amasannyalaze amangi geetaagibwa, okwonoona amaanyi n’okulinnyisa ssente. Okutereeza ensonga y’amaanyi kikekkereza amaanyi era kikuuma enkola yo obutabuguma oba okwonooneka.
Nedda, ensengekera za njawulo. Ku nkola za DC , kozesa:
Amps = Watts ÷ Volts
Ku nkola za AC , ssaako ensonga y’amaanyi:
Amps = Watts ÷ (Volts × Power Factor) .
Ensonga y’amaanyi ekakasa okubala okutuufu ku nkola za AC.
Okusooka, bala akasannyalazo:
Amps = Watts ÷ Volts
Londa breaker ewereddwa katono waggulu wa amps ze wabala. Okugeza ekyuma kyo bwe kiba kyetaaga amp 18, kozesa ekyuma ekimenya amp 20. Kino kiziyiza okutikka ebintu ebisukkiridde n’okukuuma ebintu nga tebirina bulabe.
Okubala okukyamu kuyinza okutikka circuits ekisusse, ne kivaako okubuguma oba omuliro. Ebyuma nabyo biyinza okulekera awo okukola singa tebifuna current emala. Bulijjo kebera emirundi ebiri okubala kwo oba kozesa ebikozesebwa ku yintaneeti okwewala ensobi.
Amagezi : Bw’oba tokakasa, saba omusawo w’amasannyalaze akukebere ensengeka yo oba okubalirira kwo.
