Misalai shi ne Voltage Transformer?

Mai yana Voltage Transformer?

Takardun Voltage Transformer

Voltage transformer ko kuma potential transformer, yana ƙara tsari mai yawa zuwa masu tsari mafi yawan daidai don samar da amfani da meters da kuma relays na tsarin.

Farkon Yadda Ake Amfani Da Ita

Waɗannan transformers suna taka cikin primary windings daga baya zuwa phase da kuma ground, suke yi aiki kamar wasu step-down transformers amma musamman don gidaje tsari.

Tsari Na Tsakiyar Matattaccen

Tsari na tsakiyar matattaccen na voltage transformer na musamman shine 110 V.

Matattacce

Matattacce a cikin voltage transformers sun hada da abin da suka faru a matsayin tsari da kuma alama na phase, wanda ke taimakawa da zinariya.

Is – Secondary current.

Es – Secondary induced emf.

Vs – Secondary terminal voltage.

Rs – Secondary winding resistance.

Xs – Secondary winding reactance.

Ip – Primary current.

Ep – Primary induced emf.

Vp – Primary terminal voltage.

Rp – Primary winding resistance.

Xp – Primary winding reactance.

KT – Turns ratio = Numbers of primary turns/number of secondary turns.

I0 – Excitation current.

Im – Magnetizing component of I0.

Iw – Core loss component of I0.

Φm – Main flux.

β – Phase angle error.

Sabbin Matattacce

Tsari da aka saka a cikin primary ya zama ta ƙara saboda internal impedance na primary. Sune ta shiga a cikin primary winding kuma ya zama ta ƙara proportional to its turns ratio, zuwa secondary winding. Wannan tsari na tsakiyar ya zama ta ƙara saboda internal impedance na secondary, kafin ta shiga a cikin burden terminals. Wannan shine sabbin matattacce a cikin potential transformer.
