Cov lus nug nquag nug (FAQ)
Q1: Dab tsi ntawm transformers tuaj yeem kuaj NRHG902?
A1: NRHG902 Instrument Transformer Comprehensive Tester txhawb nqa tag nrho cov chav kawm CT (P, TPY, metering, PR, PX, TPS, TPX, TPZ) thiab PT chav kawm P.
Q2: Puas yog lub tester xav tau siab -voltage input rau excitation test?
A2: Tsis yog. Siv tus qauv qis- zaus, nws tso tawm max 180 Vrms los ntsuas CTs nrog lub hauv caug voltage txog 30 kV, ua kom cov neeg siv kev nyab xeeb.
Q3: Cov txiaj ntsig kuaj tau raug xa tawm li cas?
A3: Cov txiaj ntsig tuaj yeem khaws cia sab hauv (2000 cov ntaub ntawv), xa tawm ntawm USB flash drive rau PC, thiab hloov mus rau hauv cov lus ceeb toom siv cov khoom siv PC.
Q4: Cov ntawv pov thawj dab tsi yog cov chaw tsim khoom tuav?
A4: Refine On (Hebei) Electric Power Technology Co., Ltd. tau lees paub rau ISO 9001: 2015 (Quality), ISO 14001: 2015 (Environment), thiab ISO 45001: 2018 (Kev Ua Haujlwm Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb).
