Zam'manja Zamagetsi (Digital) CT/VT Calibrator HEWD-2A

Portable Electronic (Digital) CT/VT Calibrator HEWD-2A Chithunzi Chowonetsedwa

Kuyesa Kolakwika kwa Digital Output (Ratio Error ndi Phase Error).

Yogwirizana ndi protocol IEC61850-9-1/2/2LE ndi IEC60044-FT3.

Kuyesa Kolakwika kwa Analogi (Zolakwika za Ratio ndi Vuto la Gawo).

Analogi ya kutulutsa kwachizindikiro kakang'ono.

EMC kutsatira muyezo IEC60044-8.

Technical Index

1. Mayeso olakwika a digito amagetsi (digito) CT/VT.
1) Kuyesa kwachiwerengero ndi gawo lolakwika.
2) Yogwirizana ndi IEC61850-9-1, IEC61850-9-2, IEC61850-9-2LE ndi IEC60044-FT3.
3) Yogwirizana ndi mawonekedwe osiyanasiyana a fiber fiber.
4) Holography kusanthula uthenga wa IEC61850-9-1/IEC61850-9-2.
5) Kujambula zolakwika za malo oyesera ndi kufufuza kwa data / sitolo / kusindikiza ndi mapulogalamu.
2. Kuyesa kolakwika kwa analogi pamagetsi (digito) CT/VT ndi CT/VT wamba.
1) Mayeso apakati ndi gawo lolakwika la digito CT/VT.
2) Mayeso apakati ndi gawo lolakwika la CT/VT wamba posintha kukhala siginecha yamagetsi kudzera mu chosinthira chokhazikika.
3. Mpaka kuyesa 0.2S kalasi digito CT/VT.
4. Analogi ya kutulutsa kochepa kwa chizindikiro.
5. Kusanthula kwa mafunde a Harmonic kwa chizindikiro cholowera cha digito CT/VT poyesedwa, m'badwo wa curve spectrum, mbiri ya zomwe zili munthawi iliyonse ya harmonic (mpaka 50times harmonic), ndi kuwerengera kusokoneza kwa harmonic.
6. Kusanthula kwa magawo a RMS (makulitsidwe, gawo, mafupipafupi ndi zina) za chizindikiro cholowera.
7. Nthawi yeniyeni yowonetsera mawonekedwe otuluka, mawonekedwe amtundu wa chizindikiro, polarity, sync status ndi peresenti ya mtengo pansi pa mayeso a CT/VT poyesedwa.
8. Polarity ndi kuchedwa kwa nthawi kuyesa kwa digito CT/VT pogwiritsa ntchito inbuilt PPS (kugunda pa sekondi iliyonse) ndi B code kuti litulutse chizindikiro kulunzanitsa
9. Kugwiritsa ntchito piritsi kudzera pa pulogalamu ya APP (posankha).
10. EMC kutsatira muyezo IEC60044-8.
11. Mapulogalamu apakompyuta.
1) HMI yaubwenzi komanso mawonekedwe omveka bwino.
2) Sungani zokha data yoyeserera ndikupanga lipoti loyesa.
