Tus lej no yog ib qho kev ntsuas ntawm attenuation txheeb ze rau huab cua thiab dej qhia hauv Hounsfield units (HU): CT tooj cua=-1000 HU. CT tus lej dej=0 HU.

Q: Yuav ua li cas ntsuas PT ratio?

A: PT Ratio qhov tseem ceeb tsuas yog thawj qhov hluav taws xob faib los ntawm qhov nruab nrab voltage. Piv txwv li, 4200 / 120=35. Muaj tsawg zaus, nws tseem tuaj yeem siv qhov thim rov qab PT txhawm rau nce qhov qis qis xws li 12 Vac rau 120 Vac kom muaj WattNode meter los saib xyuas 12 lossis 24 Vac lub zog noj.

Q: Vim li cas PT txuas nrog tib lub sijhawm?

A: Los ntawm kev nce tus naj npawb ntawm cov transformers sib txuas ua ke, lub peev xwm thauj khoom tuaj yeem nce ntxiv thiab cov khoom siv hluav taws xob loj tuaj yeem ua tiav. Kev ua haujlwm sib luag ntawm cov khoom siv hluav taws xob tuaj yeem txhim kho kev siv hluav taws xob, txo cov hluav taws xob pov tseg, thiab txo kev siv hluav taws xob.

Q: Qhov nruab nrab voltage ntawm CT yog dab tsi?

A: Cov kev ntsuas hluav taws xob theem nrab suav nrog: 10, 20, 50, 100, 20{{20 } }, 400, thiab 800. Cov no sib raug rau tus qauv relay lub nra hnyav ntawm 0.1, 0.2, 0.5, 1.0, 2.0, 4.0, thiab 8.0 raws. Qhov sib piv yuam kev yuav tsum tsis pub tshaj 10 feem pua ntawm ib qho tam sim no los ntawm 1 mus rau 20 lub sij hawm ntsuas tam sim no ntawm ib qho qis dua ohms.
