Paidu yog Tuam Tshoj chaw tsim khoom & chaw muag khoom uas feem ntau tsim hnub ci Cable Optical Voltages nrog ntau xyoo ntawm kev paub. Voltage yog hais txog hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hauv hluav taws xob hluav taws xob. Nyob rau hauv cov ntsiab lus ntawm lub hnub ci cables, peb feem ntau tham txog qhov ntsuas hluav taws xob ntawm lub cable, uas qhia tau hais tias qhov siab tshaj plaws qhov hluav taws xob cable tuaj yeem ua haujlwm yam tsis muaj kev puas tsuaj lossis kev puas tsuaj. Qhov ntsuas hluav taws xob no feem ntau tau teev nyob rau hauv volts (V) lossis kilovolts (kV).Yog tias koj nug txog "hnub ci cable optical voltages," nws yuav yog ib qho kev nkag siab yuam kev lossis lub npe tsis raug. Cov kab hluav taws xob hnub ci tsis cuam tshuam rau qhov hluav taws xob kho qhov muag raws li lawv tau tsim los nqa cov hluav taws xob hluav taws xob, tsis yog cov teeb liab kho qhov muag. Txawm li cas los xij, yog tias koj xav siv cov cuab yeej siv kho qhov muag fiber ntau hauv lub hnub ci zog rau cov ntaub ntawv xa mus lossis kev saib xyuas lub hom phiaj, koj yuav xav txog kev sib koom ua ke cov khoom siv kho qhov muag nrog rau cov kab hluav taws xob ib txwm siv los xa cov ntaub ntawv los ntawm cov sensors, inverter, lossis cov cuab yeej saib xyuas rov qab mus rau lub hauv paus tswj hwm.
