Njàngalem kaptëru kuuraŋ mooy nga soppi parametre kuuraŋ yu melni courant ak voltage ci siñaal kuuraŋ yuñ mëna natt, ak am parametre yiñ soxla ci liggéey bi. Li ci topp mooy jéego bu leer ci jéego yi,
1. ci nattukaayi nattukaay yi
Shunt anam : Soo boolee ab resistor bu woyof-res (00}}sistance (shunt) ci série, voltage bi ci resistor bi. Dafay jëfandikoo DC wala -frequence AC jëfandikoo loi Ohm, waaye courant bu mag mën na waral tàngoor.
: Capteur efekt: champ magnetik bi wër courant { 0}}na carrying conducteur ngir defar élément Hall bi defar voltage ci courant bi ngir mëna def nattukaay bi amul-konte. Dafay jëfandikoo ci AC/DC te amna lu baax.
Soppiration (CT): buñu sukkandikoo ci induction electromagnetik, dafay soppi courant bu mag bi ci wàll wi njëkk ci benn courant bu ndaw ci wet gi. Dafay jëfandikoo ci natt AC.
Rogowski bobine bu amul benn core magnetik. Dafay génne voltage ci indi coppite ci coppite bi am ci courant bi, ba noppi di am courant bi ginaaw boole bi. Dafa méngoo ak -frequency wala senaario yu kawe- AC yiy ñëw ci jamono, te mën na am anti{4}}saturasioŋ bu dëgër.
2. ci nattum natt
Resistor ci anam wi ñuy xaajalee voltage bi: Ci biir benn reso buy séddale voltage ci series, voltage bi dafay yéeg ba noppi natt ko. High- precision,- température drift yi soxla nañu ko.
Transformatëru Voltage (PT): Noonu la CT, dafay soppi voltage bu kawe ci voltage bu woyof te baaxna ci sistem AC yi.
Capacitor ci anam wi ñuy xaajalee voltage : voltage bu kawe dañu koy natt ci divideur biy xaaj voltage capacitor, muy lu bari ci senaario voltage wala pulse pulse.
3.
‐Ampfication ak segg : Jëfandikool amplifikatëru liggéey ngir gëna am doole siñaal yu néew doole ak jëfandikoo ay filtre yu woyof {0} Lupass ngir dindi {1} 1 } frequency bruit.
Analog-to{ {1} nga soppi (ADC): Soppi siñaal analog ci siñaal dijital yi, ba noppi tolluwaayu sampling bi dafa wara méngoo ak teorem Nyquist bi (ci anam wu néew ñaari yoon siñaal bi).
4. natt gi
Ci saasi voltage bi ak courant bi ci saasi, yokk leen ngir am doole ci saasi, ba noppi boole leen ngir am doole ju bari jiy yëngu. Ci sistem bu ñetti-, ñaari- na njuréefi njuréefi-metar wala ñetti- na ñu mëna jëfandikoo ngir xayma doole ji yépp.
5. Xam-xam ak kaaraange
Li gëna am solo mooy: Jëfandikool ay inductër wala aparey yuñ boole ngir defar ay sircuit voltage yu kawe ak yu néew.
Reylu optik: Tekki siñaal yi jaaraleko ci coupling optik ngir tere lëkkaloo kuuraŋ.
Xaralay optik bu njëkk: Jëfandikool effet Faraday ngir natt courant bi, ak performance isolation bu baax, baax ci environmaa yi voltage bu bari.
