Product Description

Darui Electric recommends for you

Our company's voltage transformer error tester is developed with new testing technology, large-scale electronic circuit design, and in accordance with relevant national regulations. The voltage transformer field tester solves the problems of high work intensity and cumbersome operation in on-site verification of voltage transformers. At the same time, the product is reliable in performance and powerful in function.

Product Features;

1.The voltage transformer field tester combines the functions of measuring voltage transformer errors using the low-voltage calibration high-voltage method and the potential difference method, facilitating on-site verification of metering devices.

2. On-site verification of voltage transformers does not require standard voltage transformers, boosters, load boxes, or voltage regulating control boxes. It uses extremely simple test wiring and operation to achieve verification of electromagnetic voltage transformers, greatly reducing work intensity and improving work efficiency, facilitating on-site transformer verification.

3、The YTC2135 voltage transformer field tester has a built-in standard voltage transformer with the same transformation ratio as the tested voltage transformer, with an accuracy of 0.02 level, accurately measuring the transformation ratio and no-load error of the tested voltage transformer. Then, combined with the test results of impedance and admittance, the error of the transformer is calculated.

4、Wide measurement range, up to 6kV/100V~220kV/V/100/V.

5、Has the functions of voltage transformer transformation ratio, DC internal resistance, and voltage load box testing.

6、Has the function of testing dual-winding voltage transformers, with two load boxes.

7、Adopts a 640×480 high-resolution large-screen LCD display, with user-friendly interface and operation design, using touch screen auxiliary operation, making operation more convenient and faster.

8、Adopts accurate software algorithms, further improving the accuracy of measurement data.

9、Has intelligent judgment of external wiring conditions, prompting wiring errors, transformation ratio errors, polarity errors, etc.

10、Automatically rounds test data and judges whether it exceeds tolerance. Data exceeding tolerance is displayed in reverse black, making the data characteristics of the transformer intuitive and clear.

11、Directly issues on-site verification conclusions, qualified or unqualified.

12、Large-scale storage can store up to 1000 items of field test data.

13、The voltage transformer field tester comes with a printer, which can print test data on-site.

14、Adopts engineering plastic mold casing, shockproof and pressure-resistant, ensuring the safety of operators and equipment during high-voltage tests on site.

The high-voltage energy metering devices in power plants and substations, as well as the energy metering devices of a large number of users, are related to the interests of power generation, transmission, supply, and users. To ensure accurate metering, inspections must be carried out in accordance with JJG1021-2007 "Power Transformers" and DL/T448-2000 "Technical Management Regulations for Energy Metering Devices".
