1. RS025-L field current transformer error tester adopts a recurrence method to measure the current transformer error, which facilitates metering device to develop field verification on site.
2. There is no need to use a standard current transformer, large current generator, load box, voltage regulating control box and large current wire to verify voltage transformer on site, and extremely simple test wiring and operation are used to verify electromagnetic current transformer, which greatly reduces working intensity and improves working efficiency, and facilitate to develop field verification of transformer.
3. RS025-L field current transformer error tester is equipped with standard current transformer with the same transformation ratio as tested current transformer, and its precision degree is0.05class, which can accurately measure transformation ratio and no-load error of testing current transformer. Then combine with impedance and admittance testing results to calculate transformer error.
4. Power supply test of pilot frequency close to power frequency is adopted, which prevents field power frequency electromagnetic radiation and serial interference.
5. Wide measuring range, able to expand to 5A/5A-25000A/5A or 5A/1A-5000A/1A.
6. With functions of testing current transformer transformation ratio and internal resistance of secondary winding.
7. It has 640×480 high-resolution large-screen LCD display, humanized interface and operation design. And touch screen is used to facilitate operation which makes operation more convenient and faster.
8. The accurate software algorithm has further improved accuracy of measuring data.
9. Able to intelligently judge external wiring state, point out wiring error, transformation ratio, polarity error, etc.
10. Automatically round off testing data, determine whether it exceeds out-of-tolerance which will be displayed through counter-black, which makes transformer data characteristics intuitive and clear.
11. Directly issue field verification conclusion of being qualified or not.
12. Large-scaled memory unit can preserve 1000 sets of field testing data.
13. Equipped with printer, able to print testing data on site.
14. Engineering plastic mold machine box has vibration resistance and pressing resistance, which ensures safety of operators and equipment.
