Vim li cas siv cov kev sim siab?
High voltages nrog cov tswv yim me me:Resonance drastically txo lub hwj chim uas yuav tsum tau los ntawm kev ntsuas mov .
Kev Ntsuam Xyuas Ntev:Haum rau cov kev ntsuas mus ntev (e {{0} g .}}) yuav tsum tau los ntawm cov qauv {}}
Voltage stability:Lub kaw lus cia li hloov kho zaus kom tswj hwm resonance txawm tias me ntsis hloov pauv hauv capacitance lossis kub .
Sinusoidal voltage waveform:Qhov tseem ceeb rau kev tawm tsam ib leeg thiab kom tsis txhob muaj kev puas tsuaj los ntawm cov tsis muaj kev puas tsuaj los ntawm kev ua txhaum hluav taws xob tsis yog {}}
Cov cuab yeej Portable:Cov tshuab resonant tuaj yeem ua kom tau compact thiab trailer-mounted rau hauv-site kuaj {}
