Iindaba

1. Iziko lomthwalo ngokubanzi linesitishi okanye isikhululo sokuhambisa, kwaye ukunyuka okanye ukuhla kwe-voltage kugqitywe ngu (i-transformer).

2, "i-frequency yamandla" yaseTshayina yi (50)Hz, ukutenxa rhoqo okanye thabatha (0.2)Hz, ukutenxa kombane dibanisa okanye thabatha (5%)

I-3, inkqubo yamandla e-AC yesigaba sesithathu kwindlela yokusebenza yonikezelo lwamandla olungathathi hlangothi (neutral grounding), (i-neutral grounding through impedance) inkqubo, (i-neutral direct grounding) inkqubo.

I-4, i-factory low-voltage power distribution system ye-wiring mode yi (radial), (trunk), (ixutywe), (ring).

I-5, ukuchithwa kwe-arc (ukukhutshwa kwe-thermoelectric), (ukukhutshwa kombane ophezulu), (i-collision dissociation), (i-thermal dissociation).

6. Kumthwalo oyintloko, ngokukodwa umthwalo obalulekileyo, ukongeza (ezimbini) unikezelo lwamandla oluzimeleyo, kufuneka longezwe (umbane ongxamisekileyo), kwaye akukho lunye ukufikelela komthwalo.

7. Umthwalo obalwayo ngumthwalo ocingelwayo wezixhobo zombane ezikhethiweyo ngokwe (imeko yokufudumala).

I-8, i-drop yi-fuse ye-(non - flow limited) fuse.

9. Isixhobo sokukhusela umbane Bonke abamkeli bombane kufuneka baqhagamshelwe kunye nesixhobo sokumisa phantsi (ukukhokela).

I-10, iimfuno ezisisiseko zesixhobo sokukhusela i-relay (ekhethiweyo), (ngokukhawuleza), (ukuthembeka), (uvakalelo).

I-11, kumandla ombane kumgca wekhabhinethi yokulinganisa okhethekileyo, kuyimfuneko ukufakela ukubalwa kweendleko zombane zesigaba sesithathu (esisebenzayo) kunye (esisebenzayo) semitha yeyure.

12. Kwiisekethe zefektri, uxhulumaniso phakathi kwesekethe ephambili kunye nesekethe yesibini ngokuqhelekileyo yenziwe yi-transformer yangoku kunye ne-voltage transformer.

13. Esona sakhiwo siqhelekileyo sothungelwano lwangaphandle lweefektri kunye namashishini (umgca we-overhead) kunye (ikhebula).

14. Imisebenzi ye-transformer isetyenziselwa ikakhulu (umlinganiselo wobungakanani bombane) kunye (nokukhusela i-relay).

Eyona ndlela ixhaphakileyo yokungaphumeleli kwiinkqubo zamandla (i-short circuit).

16. Isixhobo sokukhusela i-Overcurrent sahlulahlulwe kwiindidi ezimbini (umda wexesha elimiselweyo) kunye (umda wexesha elibi).

17. Indlela yokuphucula amandla endalo kukusebenzisa amanyathelo okunciphisa okufunekayo (amandla asebenzayo) wezixhobo zombane ukuphucula amandla ayo.

18. Umgca wamandla ohambisa amandla ombane ukusuka kwiziko lomthwalo kumthengi ngamnye ubizwa ngokuba (ukusabalalisa) umgca.

19. Amandla ombane asezantsi osasazo lwe-voltage kumzi-mveliso amiselwa ubukhulu becala bubume besixhobo sombane somzi-mveliso.

I-20, izibonakaliso eziphambili zomgangatho wokunikezelwa kwamandla zi (i-voltage), (i-frequency), (i-waveform), (ukuqhubeka kokunikezelwa kwamandla).
