Kev Ntsuas Siab (HV) yog ib qho kev kuaj mob siab yog ib txoj kev kuaj mob thiab kev tswj hwm zoo siv los siv lub rwb thaiv tsev muaj zog ntawm cov khoom hluav taws xob los ntawm
Thov ib qho hluav taws xob siab dua nws qib ntsuas.
Kev kuaj siab siab yog qhov tseem ceeb rau kev ua kom zoo thiab kev nyab xeeb hauv lub zog nruab. Kev xaiv voltage tsim nyog, ntev, thiab cov txheej los ua kom muaj kev cia siab, tiv thaiv tsis tiav, thiab cov qauv ua raws cai. Lub HIPOT Test, muab tau los ntawm lub sijhawm muaj peev xwm xeem tau, yog daim ntawv thov ncaj qha ntawm cov hluav taws xob siab rau ib chav nyob hauv qab ntsuas. Qhov kev xeem voltage feem ntau yog ntau dua li cov niaj zaus ua haujlwm voltage nyob rau hauv thiaj li yuav ntxhov siab cov khoom dielecric ntawm cov cuab yeej ua raws li kev sim.
Ntau yam kev siv hauv hluav taws xob engineeringering For example, high DC voltages of at least 100 kV are needed for electron microscopes and X-ray units, while electrostatic precipitators and particle accelerators require DC voltages of several kilovolts or even megavolts.
