Product Introduction

Power plant and substation high-voltage energy metering devices, and a large number of users of energy metering devices, related to power generation, transmission, power supply and the interests of multiple users. To ensure accurate measurement, must be in accordance with JJG1021-2007 "power transformer" and DL / T448-2000 "power metering device technical management procedures" for testing.

Our company's NAQY voltage transformer field tester calibration device is based on high-end test technology, large-scale electronic circuit design and in line with relevant national regulations developed. It solves the on-site verification voltage transformer work intensity, operation cumbersome problem, at the same time the product performance is reliable, powerful.

Equipment characteristics

1, NAQY voltage transformer field test instrument calibration device also has a low-law high-voltage measurement of voltage transformer error and potential difference measurement of voltage transformer error function in one, to facilitate site measurement device on-site verification work.

2, on-site verification voltage transformer without standard voltage transformer, booster, load box and voltage control box, using a very simple test wiring and operation of the electromagnetic voltage transformer verification, greatly reducing the work intensity and Improve the work efficiency, facilitate the scene to carry out on-site verification transformer.

3, NAQY voltage transformer field tester calibration device, the internal voltage transformer with the measured transformer with the same standard voltage transformer, the accuracy of 0.02, accurate measurement of the measured voltage transformer ratio and No - load error. And then combined with the impedance and admittance of the test results to calculate the transformer error.

4, measuring a wide range, you can to 6kV / 100V ~ 220kV / V / 100 / V.

5, with a voltage transformer ratio, DC resistance and voltage load box test function.

6, with a dual winding voltage transformer test function, with two load boxes.

7, with 640 x 480 high-resolution large-screen LCD display, with a user-friendly interface and operational design, the use of touch-screen auxiliary operation, the operation becomes more convenient and fast.

8, the use of accurate software algorithms, measurement data to further improve the accuracy.

9, with intelligent judgments external wiring status, suggesting that wiring errors, variable ratio, polarity error.

10, automatically test the data for the whole, and to determine whether the tolerance, ultra-poor data using anti-black display, the transformer characteristics of the data intuitively clear.

11, directly issued by the site test conclusions, qualified or unqualified.

12, large-scale memory can store up to 1000 field test data.

13, with a printer, you can print test data field.

14, the use of engineering plastic mold chassis shock, anti-pressure, high-pressure test to protect the scene when the operator safety and equipment safety.
