FAQ
Q: Puas yog 300Hz tseem yog qhov kev sim ncaj ncees rau 50Hz cable? Vim li cas thiaj tso cai rau qhov ntau yam tsis yog qhov tseeb 50Hz?
A: Qhov ntau yog kev sib haum xeeb engineering rau Equivalence thiab Portability. Kev tshawb fawb qhia tau hais tias XLPE treeing cwj pwm yog ze li ntawm 50Hz nyob rau hauv pawg no.
Q: Vim li cas thiaj yuav 160kV Resonant System thaum VLF me me tuaj yeem ua haujlwm?
A: VLF yog qhov zoo rau 35kV cables, tab sis hits ib phab ntsa ntawm 110kV+. Resonant sets yog ntau npaum li cas ntawm high voltages.

Q: Puas yog qhov zaus ntawm Hipot qhov tseem ceeb rau Kev Saib Xyuas Ib Feem (PD)?
A: Yog lawm. Kev ua PD nyob ntawm qhov Voltage Gradient (dv/dt). Cov frequencies siab dua ua rau muaj qhov ci ntsa iab ntau dua.
Zaus vs. PD Accuracy:
• Ntawm 200Hz: High dv/dt ua rau voids ntau zaus/sec. Waveforms phim 50Hz kev pabcuam kom raug.
• Ntawm 0.1Hz: Kev hloov hluav taws xob qeeb yuav tsis ua rau qee qhov tsis xws luag (False Negative).
Q: Kuv puas tuaj yeem mus rau 400Hz rau ib qho luv luv cable? Dab tsi yog qhov txaus ntshai?
A: Tsis yog. Muaj zaus yog yeeb ncuab ntawm cov khoom siv hluav taws xob hnyav vim yog thermal thiab poob yam.
Risks of >300Hz:
❶ Eddy Tam Sim No Losses: Lub zog pov tseg hauv cov tso tsheb hlau luam / cov ntxaij vab tshaus nce nrog zaus squared.
❷ Cov nyhuv ntawm daim tawv nqaij: Tam sim no tsuas yog ntws ntawm "daim tawv nqaij," tsa AC tsis kam thiab poob Q- yam.
❸ Dielectric Cua sov: Cov cua sov sab hauv tuaj yeem ua rau thermal tawg ua ntej qhov kev xeem xaus.
Q: Thaum kuv nias Auto-Tune, VFD ua dab tsi thaum lub sijhawm 10-thib ob cheb?
A: Lub VFD tab tom ua qhov Zaus Sweep kom pom qhov tseeb qhov siab tshaj qhov "hump."
Scan Cycle:
1. Scan: VFD ramps ntawm 20Hz mus rau 300Hz ntawm qhov tsawg voltage.
2. Peak Detect: Saib xyuas exciter tam sim no vs cov zis voltage.
3. Xauv: Lub computer "locks" zaus qhov twg cov zis voltage peaks.
