I. Yam khoom tseem ceeb qhia
1, DC tsis kam:
(1) Cov ntsiab lus tseem ceeb:
Kev soj ntsuam peb-theem: 5A + 5A thiab 1A + 1A
Kev ntsuam xyuas ntau yam: 5A: 10mΩ mus rau 4Ω
1A: 1Ω txog 20Ω
Kev xeem sib cais: 10A, 5A, 1A
Kev ntsuam xyuas ntau yam: 10A: 500.0μΩ ~ 1Ω
5A: 10mΩ mus rau 4Ω
1A: 1Ω txog 20Ω
Kev daws teeb meem: 0.1μΩ
Ntsuas kev ntsuas: 0.2
(2) Lub ntsiab nta:
Peb theem kev simultaneous xeem thiab tsis siv neeg lub cev tsis sib xws;
Tag nrho cov siab thiab tsawg voltage tam sim no thiab cov kab kev xeem muaj peev xwm cuam tshuam nrog rau qhov kev hloov ua ib zaug. Nws tsis tsim nyog los cuam tshuam cov kab ntawv xeem thaum xeem.
Rau qhov ntsuas qhov nruab nrab ntawm kev sib tw nrog lub nruab nrab nruab nrab ntawm kev sib tw, peb theem kev simultaneous test yuav siv los kuaj qhov tsis ua hauj lwm ntawm A0, B0, thiab C0 phases, uas kom txhij txhua lub sijhawm xeem.
Rau qhov ntsuas tsawg-voltage ntawm peb-theem tsib-theem qis-voltage nrog lub kaum sab nrauv-sib txuas ua ke, txoj kev los ntawm kev sib nqus cov kev pabcuam tsis raug siv, thiab kev xeem sai yog ceev;
Nws tuaj yeem tso saib thiab sau tag nrho cov ntawv xeem ntawm kev sib tw siab, nruab nrab thiab tsis tshua muaj zog ntawm cov tshuab luam ntawv, thiab yuav xam cov theem ntawm peb theem. Nws kuj tseem tuaj yeem luam cov ntaub ntawv coj los hloov dua siab tshiab rau cov cua sov.
Muaj lub zoo meej rov qab-EMF tiv thaiv kev ua haujlwm;
Qhov ntsuas yuav tuaj yeem khaws cia cov ntaub ntawv xeem.

2, luv Circuit Court impedance:
(1) Cov ntsiab lus tseem ceeb:
Kev ntsuas qhov siab muaj zog: 5 ---- 400V; Ntsuas kev ntsuas: 0.2
Kev ntsuas tam sim no: 0.1 --- 10A; Ntsuas kev ntsuas: 0.2
(2) Lub ntsiab nta:
Ib-theem 220V tsawg-voltage fais fab mov yog siv los siv tau tam sim no mus rau AB, BC, thiab CA windings ntawm lub transformer, thiab cov ntaub ntawv yog sau synchronously thiab cov feem pua impedance yog hloov dua siab tshiab.
Cov qauv peb-theem nrog Y / △, Y / Y, thiab △ / Y kab hlau txuas tau txuas cov cables ib zaug thiab xaiv peb theem ntsuas kom tau ntsuas cov ntaub ntawv thiab yuav xam cov impedance thiab impedance uas tsis.
Thaum siv ib hom txheej txheem ntawm qhov ntsuas raws li kev ua theem peb theem, cov tswv yim yuav tsum yog 1/3 ntawm cov peev txheej.
Nws tuaj yeem tso saib thiab luam tawm tag nrho cov ntawv xeem ntawm qhov kev hloov tshuab;
Qhov ntsuas yuav tuaj yeem khaws cia cov ntaub ntawv xeem.

3, on-load hloov:
(1) Cov ntsiab lus tseem ceeb:
Tawm ziag no: 0.4A
Kev daws teeb meem: 0.01Ω
Txoj kev hloov tsis ua hauj lwm: 1Ω ~ 30Ω
Hloov sijhawm: 0 ~ 200ms
Kev Ntsuas Ua Tau: Kev Hloov Xeem (5% + 0.2Ω) Simultaneous Time 0.1ms
(2) Lub ntsiab nta:
Peb lub tebchaws tam sim no;
haib, muaj peev xwm paub qhov kev hloov ntawm kev hloov mus los, kev hloov lub sij hawm, kev hloov ntawm kev hloov, peb tsis muaj tib lub sijhawm ntsuas;
Ntsuas cov kev xeem thiab kev ntsuam xyuas;
Nws tuaj yeem tso saib thiab sau cov qauv kev sib tw ntawm kev hloov mus rau qhov hloov ntawm kev hloov;
Qhov ntsuas yuav tuaj yeem khaws cov ntawv pov thawj ntawm cov ntawv;
Qhov ntsuas tau nruab nrog ib qho kev tawm ncaj nruab nrab thiab ib qho kev tiv thaiv kev tiv thaiv ntawm kev tiv thaiv overvoltage. Peb theem relay tiv thaiv tester
