Me kana Current Transformer?

Me ke nan Current Transformer?

Takaitaccen Current Transformer

Current transformer (CT) shine instrument transformer inda amfani da shi wajen kawo current na farko zuwa current na biyu, kuma ya fi shi yawan haske ba tare da fase.

Klasu na Dukkirin CT

Klasu na dukkirin current transformer ya kawo wani takam tsari game da yadda adalci shi ya kawo current na farko zuwa current na biyu, wanda ya fi karfi don dukkiri mai inganci.

Siffarun Yadda Ake Amfani Da Shu

Current transformers sun yi aiki daga siffarin power transformer, inda current na farko shine current na system, kuma current na biyu ya kawo wannan current na farko.

Abubuwan Tsarin Haske a Current Transformer

Abubuwan tsarin haske a current transformer zai faru idan current na farko bai samu tasirin hakan a current na biyu saboda abubuwan hasken core.

• Is – Current na biyu.

• Es – EMF na biyu na gida.

• Ip – Current na farko.

• Ep – EMF na farko na gida.

• KT – Tsarin turns = Jumlah na turns na biyu / jumlah na turns na farko.

• I0 – Current na excitation.

• Im – Komponentin magnetizing ta I0.

• Iw – Komponentin core loss ta I0.

• Φm – Main flux.

Rike Abubuwan Tsarin Haske a CT

• Amfani da core na high permeability da low hysteresis loss magnetic materials.

• Daga cikin rated burden, za a iya daɗi value na daban-daban da actual burden.

• Jin daɗi length of flux path da kuma increase cross-sectional area of the core, minimize joint of the core.

• Lowering the secondary internal impedance.
