1) Load Capacity: Raws li nominal voltage thiab tam sim no ratings, lub system yuav tsum tau raws li cov kev cai nyob rau hauv tag nrho cov ntau yam ntawm xoom load mus rau tag nrho cov load;
2) High Voltage Stability: Voltage fluctuations yuav tsum nyob twj ywm nyob rau hauv predetermined txwv nyob rau hauv lub teev voltage ntau yam;
3) High Load Stability: Load fluctuations yuav tsum nyob twj ywm nyob rau hauv predetermined txwv nyob rau hauv lub teev tam sim no load range;
4) Qhov tseeb: Yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov kev sim siab;
5) Kev ntseeg tau: Yuav tsum siv cov khoom zoo siab -cov khoom zoo thiab cov khoom siv hluav taws xob txhim khu kev qha kom muaj kev ruaj ntseg thaum lub sij hawm ntev - ua haujlwm thiab siv;
6) Tsim: Yuav tsum ua kom zoo nkauj zoo nkauj thiab cov neeg siv- tus qauv tsim tus phooj ywg, nrog qhov ntev thiab cov lus qhia tshwj xeeb kom haum rau cov kev xav tau;
7) Kev Tiv Thaiv Kev Nyab Xeeb: Yuav tsum muaj ntau yam kev tiv thaiv kev nyab xeeb, xws li overcurrent, overvoltage, undervoltage, thiab luv- tiv thaiv Circuit Court.
