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, powersupplyandthe interests of multiple users. In order to ensure accurate measurement must be in accordance with SD109 "power measurement device inspection regulations" and DL / T448-2000 "powermeasurementdevicetechnical management procedures" for testing.

My company's NAQL current transformer field tester calibration device is based on high-end test technology, large-scale electronic circuit design and in line withrelevantnationalregulations developed. It so*es the field test current transformer, voltage transformer work intensity, the cumbersome operation of the problem, while the product performance,reliable,powerful.

MainFeatures

1, NAQL current transformer field test device calibration device also has a recursive method to measure the current transformer error, the potential differencemeasurementofvoltage transformer error function in one, to facilitate site measurement device on-site verification work.

2, on-site test current transformer without standard current transformers, booster, load box, voltage control box and high current wire, using a very simple testwiringandoperation of the current transformer verification, greatly reducing the work Strength and improve the work efficiency, facilitate the site to carry out field test transformer.

3, NAQL current transformer field tester calibration device within the equivalent of the measured current transformer with the transformation ratio of thestandardvoltagetransformer, the accuracy can reach 0.05, accurate measurement of the measured current transformer ratio And no-load error. And then combined with the impedance and admittance of thetestresults tocalculate the transformer error.

4, close to the frequency of the different frequency power supply test to prevent field frequency electromagnetic radiation and series interference.

5, measuring a wide range, you can to 5A / 5A ~ 25000A / 5A or 25A / 1A ~ 5000A / 1A.

6, with the current transformer ratio, the secondary winding resistance test.

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,theoperationbecomes 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 ofthedataintuitively 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.
