Los ntawm kev txheeb xyuas qhov sib piv ntawm cov hluav taws xob tiv thaiv tam sim no mus rau lub peev xwm tam sim no nyob rau hauv 0.1Hz excitation, lub cuab yeej muab ntau qhov ntsuas ntawm rwb thaiv tsev degradation. Cov txiaj ntsig kev ntsuas tau muab piv rau cov qauv tsim, suav nrog kev sib txawv ntawm tus qauv, txoj kab nqes, thiab qhov ntsuas qhov ntsuas, txhawm rau txiav txim siab qhov xwm txheej rwb thaiv tsev zoo li qub, pom zoo ua raws li - nce, lossis yuav tsum tau ua tam sim.

2. Advanced Digital Control Architecture
Ua nyob ib ncig ntawm lub siab -kev ua tau zoo ARM7 microcontroller nrog siab - ceev ADC tau txais circuitry, HVA30 siv cov zaus hloov pauv digital thiab kaw-loop tsis zoo tawm tswv yim tswj. Qhov kev tsim no tshem tawm cov teebmeem tshwm sim capacitive thiab ua kom ruaj khov, distortion- cov zis sinusoidal pub dawb thoob plaws tag nrho cov khoom thauj.

3. Kev Xeem Ua Haujlwm Zoo Tshaj Plaws
Cov cuab yeej tswj hwm lub voj voog kev sim ua tiav: tus kheej- kuaj xyuas tus kheej, ntsuas qhov ntsuas hluav taws xob- nce, qhov tsis tu ncua- tso zis tawm, tsis siv neeg kaw, thiab kev tso tawm capacitive. Cov neeg ua haujlwm tsuas yog teeb tsa cov ntsuas ntsuas, suav nrog qhov ntsuas hluav taws xob, zaus, lub sijhawm, thiab kev tiv thaiv kev txwv, thiab pib ua ntu ntu ntawm lub vijtsam kov.

4. Ntau-Mode Output Flexibility
Txhawb VLF AC sinewave, VLF AC squarewave, DC +/- polarity, thiab lub tshuab nqus tsev ntsuas hom. Kev xaiv zaus ntawm 0.01 Hz txog 0.1 Hz hauv 0.01 Hz nce ntxiv tso cai rau kev ua kom zoo rau cov qauv sib txawv thiab kev thauj khoom.

5. Kev Tiv Thaiv Kev Tiv Thaiv
Ntau-tier tiv thaiv suav nrog tshaj-voltage tiv thaiv, siab-voltage- sab dhau- tiv thaiv tam sim no, thiab qis-voltage- sab dhau- kev tiv thaiv tam sim no, nrog lub sij hawm teb cov lus teb tsawg dua lossis sib npaug li 10 ms. Tus maub los txuas rau lub siab -voltage generator ntawm optical cais, ua kom tus neeg teb xov tooj muaj kev nyab xeeb.

6. Ntawm -Site Data Management
Nruab nrog 7-inch capacitive touchscreen qhia qhov tseeb-lub sij hawm voltage thiab tam sim no waveforms thiab kuaj cov ntaub ntawv. Built-in thermal tshuab luam ntawv tsim cov ntawv xeem tam sim. Lub cim xeeb sab hauv khaws cia txog 50 daim ntawv tshaj tawm thiab 40 qhov kev xeem ua ntu zus; xaiv USB flash drive expands cia indefinitely. PC software, HVR Control Center, tso cai rau cov ntaub ntawv xa tawm, tshuaj xyuas, thiab tshaj tawm kev tsim tawm.

7. Rugged, Portable Tsim

VLF tiam
Lub WHVA30 ntiav cov kev hloov pauv digital zaus los ua kom muaj 0.1Hz lossis hloov pauv zaus siab -voltage sinusoidal waveform los ntawm tus qauv AC mains input. Los ntawm kev txo qhov ntsuas zaus mus rau 1/500 ntawm lub zog zaus, lub zog reactive xav tau ntawm lub peev xwm loads txo qis proportionally, tso cai rau lub teeb yuag tsim uas hloov loj heev series -resonant lossis lub zog- zaus sim transformers.

Tan Delta Kev Ntsuas
Rau ib lub cable nyob rau hauv kev sim, cov rwb thaiv tsev tuaj yeem ua qauv raws li kev sib xyaw ua ke ntawm rwb thaiv tsev, R, thiab capacitance, C. Raws li AC excitation:

• Resistive tam sim no, los yog to, yog nyob rau hauv theem nrog voltage thiab qhia tias rwb thaiv tsev degradation.
• Capacitive tam sim no ua rau voltage los ntawm 90℃thiab yog proportional rau cable ntev thiab hom.

Qhov poob lub kaum sab xis δ yog lub kaum sab xis uas nws tangent sib npaug ntawm qhov sib piv ntawm cov resistive rau capacitive tam sim no:

Tan δ=I_resistive / I_capacitive

Qhov siab dua Tan δ tus nqi qhia tau tias muaj kev puas tsuaj ntau dua thiab ua rau kev laus sai. Lub HVA30 ntsuas Tan δ ntawm ntau theem voltage, 0.5U₀, 1.0U₀, thiab 1.5U₀, thaum lub sij hawm sim ua ntu zus thiab sib piv cov txiaj ntsig tawm tsam cov txheej txheem rau kev xeem dhau lossis tsis ua tiav.

Lub kaw lus suav nrog arc-kev tswj kev kub hnyiab thiab arc- tua cov hom kev mus txawv tebchaws, tso cai rau kev tswj xyuas qhov tsis raug lossis mus rau tam sim ntawd thaum kuaj pom arc, tiv thaiv ob qho tib si hauv kev sim thiab tus neeg ntsuas nws tus kheej.
