Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov khoom siv ntsuas hluav taws xob thib ob sib txawv nyob ntawm nws hom tshwj xeeb, tab sis lub hauv paus ntsiab lus tseem ceeb yog ua raws li kev ntsuas hluav taws xob los ntsuas qhov tseeb thiab kev nyab xeeb ntawm qhov tseem ceeb ntawm qhov ntsuas hluav taws xob. Cov hauv qab no yog cov qauv kev ua haujlwm ntawm ntau hom khoom siv:
Tam sim no Transformer Secondary Load Tester:
Siv los ntsuas qhov nruab nrab ntawm qhov tam sim no transformers (CTs) thiab voltage transformers (PTs). Nws siv lub teeb liab kuaj rau qhov thib ob Circuit Court, ntsuas qhov voltage thiab tam sim no, thiab suav cov tsis xws li impedance, nkag, tsis kam, thiab reactance. Nws siv clamp- ntawm ammeter sampling thev naus laus zis kom ua tiav qhov kev ntsuas tsis cuam tshuam thiab txhawb nqa dual- hom impedance thiab kev ntsuas nkag, ua kom muaj txiaj ntsig zoo thiab nyab xeeb ntawm - qhov chaw sim.
Secondary Voltage Drop thiab Load Measuring Instrument:
Integrate voltage poob thiab load xeem functions. Kev ntsuas qhov ntsuas hluav taws xob thib ob siv qhov kev ntsuas qhov sib txawv, ib txhij tau txais qhov voltage amplitude thiab theem ntawm PT tso zis thiab lub zog ntsuas lub davhlau ya nyob twg, xam qhov sib txawv qhov sib txawv, theem sib txawv, thiab kev ua yuam kev. Kev ntsuas qhov ntsuas thib ob siv cov cim ntsuas ntsuas, ua ke nrog siab -cov qauv ntsuas qhov tseeb thiab cov teeb liab ua cov algorithms (xws li FFT tsom xam) los tiv thaiv kev cuam tshuam thiab txhim kho qhov tseeb. Cov cuab yeej siv niaj hnub no siv GPS / BeiDou synchronization lossis xoom tam sim no-hloov synchronization thev naus laus zis kom ua tiav tus tswv wireless- kev sib txuas lus qhev, zam kev xaim ntev -.
Secondary circuit resistance testers, raws li cov
DC voltage poob txoj kev (R=U/I), siv lub zog loj tam sim no (piv txwv li, 100A) rau hauv Circuit Court nyob rau hauv kev sim (xws li, Circuit Court breaker hu), ntsuas lub feeb voltage poob hla nws. Plaub - davhlau ya nyob twg (Kelvin) txoj kev xaim hluav taws xob tshem tawm cov kev cuam tshuam ntawm cov hlau lead, yog li suav cov nqi hluav taws xob tsis zoo. Txoj kev no ua raws li cov kev cai ntawm kev tiv thaiv kev ntsuas hluav taws xob thiab tau siv dav hauv kev kho lub tshuab hloov pauv.
Cov cuab yeej no feem ntau siv siab - daws teeb meem ADCs, digital filtering technology, thiab ntse algorithms, tswj kev nyeem ntawv ruaj khov txawm tias nyob hauv ib puag ncig muaj zog electromagnetic, kom ntseeg tau tias muaj kev ntseeg siab ntawm lub zog tiv thaiv kev tiv thaiv thiab ntsuas ntsuas.
