Cov khoom siv hluav taws xob thiab hluav taws xob tuaj yeem cuam tshuam los ntawm qhov hluav taws xob poob, kev cuam tshuam luv luv, lossis qhov hloov pauv ntawm lub zog hluav taws xob.
Voltage dips / sags, kev cuam tshuam luv luv yog tshwm sim los ntawm kev ua tsis tiav ntawm daim phiaj hluav taws xob thiab cov chaw siv hluav taws xob lossis kev hloov pauv loj tam sim ntawd. Qee zaum, yuav muaj ob lossis ntau qhov sib law liag lossis cuam tshuam. Kev hloov hluav taws xob yog tshwm sim los ntawm kev hloov pauv tsis tu ncua ntawm cov khoom thauj khoom txuas nrog kab sib chaws. Yog tias EUT tsis tuaj yeem teb tau raws sijhawm rau kev hloov pauv ntawm lub zog hluav taws xob, nws yuav ua rau muaj qhov tsis zoo. Voltage dips generators yog siv los ntsuas qhov ua tau zoo ntawm cov khoom siv hluav taws xob thiab hluav taws xob thaum raug voltage dips / sags, cuam tshuam luv luv, thiab hloov hluav taws xob.

Voltage dip typical shape
Voltage Dips Test:
Rau qhov tso zis hluav taws xob ntawm 80% ntawm tus nqi nominal, cov kev xav tau saum toj no tsuas yog yuav tsum tau txheeb xyuas qhov siab tshaj ntawm 5 s ntev.
Rau cov zis voltages ntawm 70% thiab 40% ntawm tus nqi nominal, cov kev cai saum toj no tsuas yog yuav tsum tau xyuas kom ntev li 3 s.
Rau cov zis hluav taws xob ntawm 40% ntawm tus nqi nominal nws tau lees paub los txheeb xyuas cov kev cai thauj khoom ntawm 200 V rau 240 V nominal voltage lossis ntawm 100 V rau 120 V nominal voltage.
Lub sij hawm nce thiab poob, nrog rau kev sib tw thiab qis qis, yuav tsum tau txheeb xyuas qhov hloov pauv ntawm 9{2}} degree thiab 27{11}} degree, ntawm 0% mus rau 100%, 100% mus rau 80%, 100% rau 70%, 100% txog 40%, thiab 100% rau 0%.
Lub kaum sab xis qhov tseeb yuav tsum raug txheeb xyuas rau kev hloov ntawm {{0}} % mus rau 100% thiab 100% rau 0%, ntawm cuaj theem kaum ntawm 0 degree mus rau 360 degree hauv 45 degree increments. Nws tseem yuav raug txheeb xyuas qhov hloov ntawm 100% mus rau 80% thiab 80% mus rau 100%, 100% mus rau 70% thiab 70% rau 100%, nrog rau ntawm 100% mus rau 40% thiab 40% rau 100%, ntawm 90 degree thiab kub 180 degree.
Lub EUT yuav tsum raug kuaj rau txhua qhov kev xaiv ua ke ntawm qib xeem thiab lub sijhawm nrog ib ntu ntawm peb qhov kev cuam tshuam / cuam tshuam nrog lub sijhawm ntawm 10 s yam tsawg kawg nkaus (nruab nrab ntawm txhua qhov kev sim). Txhua tus neeg sawv cev hom kev ua haujlwm yuav tsum raug sim.
Rau kev cuam tshuam luv luv, lub kaum sab xis yuav tsum tau txhais los ntawm pawg neeg tsim khoom raws li qhov phem tshaj plaws. Thaum tsis muaj kev txhais, nws raug nquahu kom siv 0 degree rau ib theem.
Rau qhov kev ntsuam xyuas luv luv ntawm peb-theem tshuab, tag nrho peb theem yuav tsum tau sim ib txhij. Rau qhov ntsuas hluav taws xob dips ntawm ib-theem systems, qhov voltage yuav tsum raug kuaj.
Rau qhov ntsuas qhov ntsuas hluav taws xob ntawm peb-theem nrog nruab nrab, txhua tus neeg qhov hluav taws xob (phase-rau-nruab nrab thiab theem-rau-theem) yuav tsum tau sim, ib zaug ib zaug.
Daim duab: Phase-to-neutral thiab theem-rau-theem sim ntawm peb-theem systems
