HZCT Current Transformer Volt Ampere Karakteristisk Tester

Resumé

The device is a new generation of innovative CT, PT test instrument which is launched market after a lot of market research and through the identification of strict professional testing and certification authorities. Device adopts high performance processor and microcomputer control architecture, the advanced manufacturing technology ,which ensure the stable and reliable product performance, complete functions, high degree of automation, high testing efficiency. It is in leading level in the domestic and the professional testing equipment of relay protection and high voltage insulation industry to test the current transformer and voltage transformer. Transformer volt ampere characteristics comprehensive test instrument is a fully automated PT, CT testing instrument, the instrument can accomplish test which include CT PT volt ampere characteristic of test, CT PT polar polarity test, CT PT ratio and polarity ratio and polarity test, automatic calculation of arbitrary point CT error curve, CT/PT ratio than the poor results of parameters. The instrument can automatically collect, analyze, store and print the test data, and it can also be stored by the U disk. In addition, the monitor uses 8 inch color large screen, high resolution 800600, full touch operation, real-time display test curve, observe test case immediately, so that the test personnel to judge the failure of the test. Test report not only tell the fine test curve, but also listed test data in accordance with the arrangement of the preferred number, and indicate the test time and print time, so can be used as the original test data. This product is suitable for the field test and calibration of all kinds of CT and PT because of its large output capacity and full function.

Vigtigste tekniske funktioner:

1. Fuldautomatisk testinstrument

 Simply set the highest output voltage and the maximum output current, the instrument can start from zero to automatically boost or rise for a variety of tests. The test data, the curve of the volt ampere characteristic curve, the 10 percent and the 5 percent error curve are recorded automatically, and the turning point value is calculated automatically. Eliminating manual voltage regulator, manual record sorting,tracing curves and so on cumbersome step , greatly improves the efficiency of the test. The test results can be stored in the computer, can print on spot and after printing, can also use U disk copy to computer printing processing. The operation is fast, simple, convenient and easy to grasp.

4, Ægte effektiv værdisampling

Alle spændings- og strømsignaler er sande og gyldige værdisampling, brug venligst den sande effektive værdi i tabellen til at korrigere.

5, Enkelt strømforsyning, nem at betjene

    Only need a single input power supply, AC220V, abandon the backward means of which the individual manufacturers still need 380V power to achieve the technical requirements.

6,U disk gemme

Testdataene kan overføres til pc'en gennem U-disken, behandles, vises, udskrives og gemme data og kurver med pc'en, hvilket i høj grad letter brugerrapporten.

7, dato og ur

Instrumentet leveres med systemtiden, enheden registrerer automatisk testtiden under testen for at gemme testregistreringer og se.

8, Ingen kontakt test, høj sikkerhed

Fuldt computerstyret enhed, uden manuel kontakt efter indstilling, instrumentet fuldautomatisk test, som gør det muligt for testpersonalet at være langt væk fra højspændingskredsløbet for at sikre testpersonalets sikkerhed.

9, Stor udgangskapacitet

Enkelt udgangseffekt, AC-spændingsudgang op til 2000V, strømudgang kort tid op til 25A; maksimal strøm 600A.

10, Med stor 8 tommer farveberøringsskærm LCD

Skærmopløsning ration op til 800600, høj opløsning, fuld farve touch-betjening førende indenlandsk, grænseflade baggrund drøm, testen viser direkte volt ampere kurven, test registrere data, intuitiv og praktisk. Panelet leveres med en printer, kan udskrives til enhver tid kurve- og testdata.

11, Berøringsskærmbetjening

Brug af vores virksomheds originale touch-teknologi til at fungere. Fuld annullering af panelknapper, kontakter, kontrolknap og andre konventionelle kontroller. Betjeningen er enkel og bekvem, og levetiden er lang.

12, Datalagring med ultra stor kapacitet

Each function test can store 50 groups of test data, data power loss will not be lost forever,  after test it can be printed through loading or upload to the computer to save, print. Instrument also has a single U disk data storage function, the field test data is saved to the U disk, so that the field test records unlimited storage.
