Umgaqo wesivamvo samandla ubandakanya ukuguqula iiparamitha zamandla njengangoku kunye nombane kwimiqondiso yombane enokumetwa, kunye nokufumana iiparamitha ezifunekayo ngokucubungula. Oku kulandelayo linyathelo elineenkcukacha{1}}nge{2}}ngenkcazo yenyathelo lomgaqo wayo wokusebenza:
1. Umgaqo womlinganiselo wangoku
Indlela yokumelana ne-Shunt: Ngokudibanisa i-{0}}resistance ephantsi (i-shunt) kuluhlu, umbane onqumla kwi-resistor uyalinganiswa. Isebenza kwi DC okanye -i-frequency AC esezantsi usebenzisa umthetho we-Ohm, kodwa umsinga omkhulu unokubangela ukufudumeza.
Isivamvo sesiphumo seholo Isebenza kwi-AC / DC kwaye inokwahlukaniswa okulungileyo.
I-Transformer yangoku (CT): Ngokusekwe kwi-electromagnetic induction, iguqula umsinga omkhulu kwicala eliphambili ube ngumbane omncinci kwicala lesibini. Isebenza kuphela kumlinganiselo we-AC.
Ikhoyili yeRogowski: Ikhoyili ye-toroidal ngaphandle kondoqo wemagnethi. Ikhupha i-voltage ngokunyusa izinga lokutshintsha kwangoku kwaye ifumana okwangoku emva kokuhlanganiswa. Ifanele -izihlandlo eziphezulu okanye eziphezulu{3}izehlo ze-AC zangoku kwaye inamandla okuchasa{4}}ukuhluza.
2. Umgaqo wokulinganisa umbane
Indlela yokwahlula amandla ombane ochasayo: Ngokusebenzisa inethiwekhi yolwahlulo lombane oluxhathisayo, amandla ombane aphezulu acuthwa kwaye alinganiswe. Okuphezulu-ukuchaneka,{2}}iqondo eliphantsi izixhasi zokukhukuliseka ziyafuneka.
I-Voltage transformer (PT): Ngokufana ne-CT, iguqula amandla ombane aphezulu ukuya kumbane ophantsi kwaye ifanelekile kwiinkqubo ze-AC.
Indlela yokwahlula amandla ombane eCapacitor: Amandla ombane aphezulu alinganiswa kusetyenziswa isahluli samandla ombane ecapacitor, esixhaphake kwiimeko eziphakamileyo{0} zokuphindaphinda okanye ukutyhaphaka kwamandla ombane.
3. Ukulungiswa komqondiso kunye nokusetyenzwa
Ukwandiswa kunye nokuhluza: Sebenzisa izikhulisi ezisebenzayo ukukhulisa imiqondiso ebuthathaka kwaye usebenzise izihluzo ezisezantsi{0} zokupasa ukuphelisa{1}}ingxolo enkulu.
I-Analog-ukuya{1}}kuguqulo lwedijithali (ADC): Guqula imiqondiso ye-analog kwimiqondiso yedijithali, kwaye ireyithi yesampulu kufuneka ihambelane ne-Nyquist theorem (ubuncinci ngokuphindwe kabini isantya esiphezulu sophawu).
4. Umlinganiselo wamandla
Ukwenza isampulu yombane okhawulezayo kunye nokhoyo ngaxeshanye, uziphindaphinde ukuze ufumane amandla ngoko nangoko, kwaye uzidibanise ukuze ufumane umlinganiselo wamandla asebenzayo. Kwinkqubo yesigaba sesithathu-ezimbini-indlela yeemitha okanye ezintathu-indlela yeemitha zingasetyenziswa ukubala amandla ewonke.
5. Ukuba wedwa kunye nokhuseleko
Ukwahlulwa kweMagnetic: Sebenzisa ii-inductors ezifanayo okanye izixhobo zokudibanisa imagnethi ukwahlula iisekethe zombane ophezulu kunye nophantsi.
I-Optical isolation: Ukusasaza imiqondiso ngokudibanisa i-optical ukuvala uqhagamshelo lombane.
Itekhnoloji yeFiber optic: Sebenzisa isiphumo seFaraday ukulinganisa okwangoku, ngokusebenza okugqwesileyo kokufakwa kwe-insulation, ilungele imeko yombane ophezulu.
