Terminology feem ntau siv nyob rau hauv ib feem ntawm qhov tso tawm ntsuas ntsuas

1. Kev tso tawm ib nrab
Kev tso tawm ib nrab yog hais txog qhov tso tawm ntawm ib qho chaw hauv cheeb tsam ntawm cov rwb thaiv tsev, uas tsis yog qhov nkag mus rau tag nrho cov rwb thaiv tsev. Nws muaj peb daim ntawv tso tawm: sab hauv (sab hauv nruab nrab), creeping tawm (ntawm qhov nruab nrab), thiab corona tawm (ntawm qhov kawg ntawm lub electrode).
2. Them nqi q
Instantaneously txhaj ib tug nqi ntawm cov nqi ntawm ob qho kawg ntawm cov khoom xeem, yog li ntawd qhov kev hloov ntawm lub davhlau ya nyob twg voltage ntawm lub xeem khoom yog tib yam li qhov kev hloov ntawm lub davhlau ya nyob twg voltage tshwm sim los ntawm ib feem ntawm nws tus kheej. Qhov kev txhaj tshuaj no yog qhov pom tseeb ntawm qhov tso tawm ib nrab.
3. Tso zis calibrator
Qhov pom tseeb tso tawm calibrator yog tus qauv hluav taws xob tsim hluav taws xob. Ua ntej qhov kev ntsuam xyuas, nws tso tawm cov hluav taws xob ruaj khov thiab ntxiv rau ob qho kawg ntawm cov qauv los simulate cov lus teb ntawm ib feem ntawm qhov paug tawm tester thaum tus qauv raug tso tawm raws li cov hluav taws xob no. Lub sijhawm no, kho qhov ntsuas coefficient. Txiav txim siab qhov ntau ntawm cov khoom siv hluav taws xob ib nrab txhawm rau ntsuas qhov pom tseeb tawm ntawm cov qauv hauv qab ntsuas hluav taws xob thaum lub sijhawm kuaj. Vim hais tias lub peev xwm tawm yog ntsuas tsis ncaj los ntawm kev sib piv nrog lub tshuab hluav taws xob tus qauv, es tsis yog ntsuas ncaj qha, lub peev xwm tawm tau hu ua "pom meej paug tawm".
Calibration fais fab generator yog ib qho cuab yeej tseem ceeb thaum ntsuas qhov tso tawm ib nrab, thiab nws qhov kev ua tau zoo tsis muaj feem cuam tshuam ncaj qha rau qhov tseeb ntawm cov txiaj ntsig kev xeem.
Lub calibrator pom tseeb yog tsim los ntawm calibration mem tes voltage generator thiab lub calibration capacitor nyob rau hauv series, thiab nws tsis tsuas yog muaj xws li: mem tes waveform sawv lub sij hawm, lwj lub sij hawm, internal kuj, mem tes peak nqi, calibration capacitor nqi, thiab lwm yam.
Lub sij hawm sawv ntawm qhov hluav taws xob waveform ntawm calibration mem tes voltage generator yog lub sij hawm ntawm {{0}}.1U0 mus rau 0.9U0, thiab qhov lwj lub sij hawm yog txhais raws li lub sij hawm los ntawm lub ncov tus nqi mus rau 0.1U0.
4. Kev kuaj pom impedance
Kev kuaj pom impedance yog ib qho khoom siv los khaws cov teeb liab nrhiav pom. Hauv kev siv, qhov tsim nyog nrhiav pom impedance yuav tsum raug xaiv raws li cov hom phiaj sib txawv thiab hom ntawm cov khoom ntsuas, txhawm rau txhim kho qhov rhiab heev, kev daws teeb meem, cov yam ntxwv waveform thiab teeb liab-rau-suab nrov piv ntawm ib feem ntawm kev ntsuas tawm.
5. Lub sij hawm qhov rais ( rooj vag tsev)
Lub qhov rais lub sij hawm yog ib qho khoom siv hluav taws xob tsim los tiv thaiv kev cuam tshuam cov teeb liab loj dua li ib feem ntawm qhov tso tawm los ntawm kev nkag mus rau qhov ntsuas qhov siab tshaj plaws. Vim tias qee qhov kev cuam tshuam yuav tsis raug qhia hauv qhov kev sim tiag tiag, tshwj xeeb tshaj yog nyob rau hauv qhov kev xeem, yog li kev siv lub sijhawm lub qhov rais tseem ceeb dua.
Lub hauv paus ntsiab lus ua hauj lwm ntawm lub sij hawm lub qhov rais yog faib lub elliptical scanning lub sij hawm lub hauv paus rau hauv ob qhov chaw: conduction (highlighted area) thiab cut-off (tsis-highlighted cheeb tsam), thiab cov paug pulse yog muab tso rau hauv conduction (highlighted cheeb tsam) los ntawm kev hloov lub txoj hauj lwm thiab qhov dav ntawm lub sij hawm qhov rais. , qhov cuam tshuam pulse yog teem rau qhov kev txiav tawm (qhov chaw tsis pom tseeb), lub sijhawm no lub ntsuas ntsuas yog tus nqi ntawm cov pa tawm pulse, thiab qhov cuam tshuam yuav tsis cuam tshuam rau tus nqi ntawm cov pa tawm pulse txawm tias nws loj npaum li cas. Yog hais tias ob lub sij hawm qhov rais raug kaw tib lub sij hawm, lub meter nyeem ntawv yog lub ncov tus nqi ntawm cov mem tes ntawm tag nrho cov ellipse.
