Series ZTEPT-10 Electronic Voltage Transformers
Derating
Lub ZTEPT-10 hluav taws xob voltage transformer yog ib tug tshiab 10kV hluav taws xob voltage transformer rau them, Lub transformer yog tsuas yog siv rau them cov ntse terminals thiab yog dav siv nyob rau hauv ntau yam kev faib hluav taws xob systems.
■ Ncaj qha tso zis hluav taws xob me me teeb liab, ua kom yooj yim rau cov qauv, txo qhov kev ua yuam kev, thiab txhim kho kev ruaj ntseg ntawm tag nrho cov kab ke.
■ Tsis txhob muaj cov tub ntxhais hlau, yuav tsis saturate, ntau zaus, kev ntsuas ntau, zoo linearity, tiv thaiv kev cuam tshuam muaj zog.
■ Thaum lub qhov hluav taws xob tso zis hluav taws xob yog luv luv rau zaum ob, yuav tsis muaj overcurrent lossis ferromagnetic resonance, uas tshem tawm cov teeb meem loj hauv lub zog hluav taws xob thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.

Installation & siv & cia
Ua ntej installation thiab commissioning, phau ntawv no yuav tsum tau ua tib zoo nyeem kom nkag siab txog cov qauv, cov yam ntxwv thiab kev ua tau zoo ntawm cov khoom no ua ntej ua haujlwm, thiab kev tiv thaiv thiab kev tiv thaiv yuav tsum tau txiav txim siab hauv kev ua haujlwm.
■ Lub tshuab hloov pauv tsis raug tso cai tig los yog tig rov qab thaum lub sijhawm thauj khoom thiab thauj khoom thiab thauj khoom, thiab yuav tsum tau ntsuas kev poob siab.
■ Tom qab unpacking, thov xyuas seb qhov chaw ntawm lub transformer puas puas, thiab seb cov khoom npe thiab daim ntawv pov thawj ntawm conformity yog raws li qhov tseeb.
■ Thaum lub sensor nyob rau hauv lub siab, lub hauv paus yuav tsum tau ntseeg tau nyob rau hauv lub hauv paus, thiab cov tso zis hlau lead yuav raug ncua, thiab luv luv Circuit Court yog nruj me ntsis txwv tsis pub.
■ Lub transformer hauv av hlau yuav tsum tau zoo grounded thaum lub sij hawm installation.
■ Lub sensor yuav tsum tau muab cia rau hauv qhov chaw qhuav, qhov cua, noo noo-pov thawj, shockproof thiab muaj teeb meem gas invasion chav, thiab lub sij hawm ntev cia yuav tsum tau xyuas tsis tu ncua seb lub cheeb tsam puas raws li qhov yuav tsum tau.
Ordering Information
Thaum txiav txim, thov sau cov qauv khoom, qhov tseem ceeb ntawm cov khoom siv (cov ntsuas hluav taws xob, qib raug, ntsuas qhov ntsuas thib ob) thiab ntau.yog tias muaj cov cai tshwj xeeb, thov sib txuas lus nrog lub tuam txhab
