Dab tsi yogHigh volf (tsawg zaus)?
High Voltage Vlfhais txog daim ntawv thov ntawmTsawg zaus heev zaus AC volionized (feem ntau 0.1 hz lossis qis dua)rau kev sim covRwb thaiv tsev kev sib koom ua ke ntawm High-Voltage (HV) Cables Thiab Cov Khoom Siv, xws li:
Nruab nrab voltage (MV) cables: 6-36 kV tshuab
HEEV NTSUG (HV) Cables: 66-500 kV tshuab
Transformers, cov tshuab hluav taws xob, Switchgear(qee zaum, txawm tias tsawg dua)
Vim li cas siv VLF hloov 50/60 Hz?
Ntawm lub zog zaus (50/60 hz), sim HV cables yuav tsum tauloj heev, bulky, thiab kimfais fab teeb meem . vlf tso cai rau koj los thov tib qho kev sim voltage tab sis ntawm antau zaus qis dua, txo:

Thaum tshav kub kub thiab ntxhov siab ntawm cov cable rwb thaiv tsev
VLF zaus ntau
| Hov ntau | Lub hom phiaj |
|---|---|
| 0.1 hz(feem ntau muaj) | Txheem rau VLF Test rau ibIEEE 400.2 |
| 0.05 hz rau 0.01 hz | Rau cov cable ntev dua thiab muaj peev xwm capinitance loads |

Lub ntsiab
| Yam | Kev piav txog |
|---|---|
| "High voltage vlf" | Kev sim VLF (0.1 hz lossis tsawg dua) ntawm voltages los ntawm 10 kv rau 200+ kv |
| Lub hom phiaj | Tsis-Kev Ua Phem Teb Chaws Kev Ntsuas ntawm Cable Rwb Thaiv Tsev |
| Qhov Zoo | Portable, muaj kev nyab xeeb, muaj zog-txuag tau rau 50/60 Hz AC Kuaj |
| Kev kuaj | Tuaj yeem ua kom zoo nrog ziab Δ thiab PD kuaj rau kev txheeb xyuas tob |
