Cov txheej txheem rau kev ntsuas kev ua haujlwm ntawm lub zog hloov hluav taws xob feem ntau tau teev tseg hauv cov qauv thoob ntiaj teb tsim los ntawm cov koom haum xws li International Electrotechnical Commission (IEC) thiab cov qauv hauv tebchaws xws li American National Standards Institute (ANSI) hauv Tebchaws Meskas. Cov qauv tshwj xeeb yuav tsum tau ua raws li yuav nyob ntawm seb yam xws li hom transformer, nws qhov ntsuas voltage, thiab daim ntawv thov.
Ib qho ntawm cov kev lees paub thoob ntiaj teb cov qauv rau kev ntsuas kev sib tw ntawm lub zog hloov hluav taws xob yog:
IEC 60076-1: Fais fab transformers - Ntu 1: General - Cov qauv no muab cov kev cai dav dav, cov ntsiab lus, thiab cov txheej txheem kuaj rau lub hwj chim transformers. Tshooj 9 ntawm tus qauv no, lub npe hu ua "Loading guide for oil-immersed power transformers," suav nrog cov kev cai thiab cov lus qhia rau kev xeem winding resistance.
Ntxiv nrog rau cov qauv thoob ntiaj teb, tej zaum yuav muaj cov qauv hauv cheeb tsam lossis lub teb chaws uas muab kev taw qhia txog kev ntsuas cua tiv thaiv tshwj xeeb rau ib lub tebchaws lossis cheeb tsam. Piv txwv li:
ANSI/IEEE C57.12.90: Standard Test Code rau Liquid-Immersed Distribution, Fais fab, thiab Regulating Transformers - Tus qauv no, tsim los ntawm American National Standards Institute (ANSI) thiab lub koom haum ntawm hluav taws xob thiab Electronics Engineers (IEEE), muab cov txheej txheem xeem thiab cov lus qhia rau ntau yam kev ntsuam xyuas ntawm cov kua-immersed transformers, nrog rau cov kev ntsuas winding kuj.
Nws yog ib qho tseem ceeb uas yuav tau sab laj txog cov qauv tsim nyog siv rau cov kev hloov pauv tshwj xeeb uas tau sim los xyuas kom meej tias cov txheej txheem kev sim thiab cov kev xav tau ua raws li qhov raug. Cov qauv no feem ntau piav qhia txog kev teeb tsa kev ntsuas, ntsuas txoj hauv kev, kev lees txais kev txwv, thiab lwm yam ntaub ntawv cuam tshuam rau kev ntsuas qhov ntsuas cua kom raug thiab ntseeg tau. Kev ua raws li cov qauv no yuav pab kom muaj kev sib luag, kev ntseeg siab, thiab kev ua tau zoo hauv kev sim transformer thiab kev saib xyuas.
