TKHG-Q current transformer field calibrator

TKHG-Q current transformer field calibrator is also called current transformer calibrator, transformer calibrator and transformer field calibrator. The current transformer calibrator produced by Guodian Mingke is in accordance with national standards

Measure the ratio difference and angle difference of current transformers, the current transformer field calibrator can measure the transformation ratio and polarity of the current transformer, and the current transformer calibrator can measure the actual secondary negative of the current transformer on site

Loads, etc., the current transformer calibrator has the function of saving any measurement parameters and printing the measurement results.

        The TKHG-Q current transformer field calibrator can measure the ratio and angle differences of current transformers according to national standards, and the current transformer field calibrator can measure any percentage of current between 1% and 200%

Ratio difference and angle difference; can directly measure the transformation ratio and polarity of the current transformer; can measure the actual secondary load of the current transformer on site and so on. The current transformer field calibrator adopts high-precision, automatic linearity

Regulated DC and AC power supplies; high-speed, high-reliability digital processing modules; high-precision, high-stability pre-measurement circuit to ensure the accuracy and high stability of the tester's measurement. another

In addition, the current transformer field calibrator adopts the 320x240 large LCD all-Chinese interface platform technology newly developed by our company. The current transformer field calibrator has a humanized man-machine interface, and

Shows the wiring and operation, the current transformer field calibrator has the function of saving any measurement parameters and printing the measurement results.

 1. The current transformer error field tester adopts the recursive method to measure the current transformer error, which is convenient for on-site verification of measurement devices;

       2. On-site verification of current transformers does not require standard current transformers, current transformers, load boxes, voltage regulating control boxes, and large current wires. Simple test wiring and operation are used to achieve current transformers

The verification greatly reduces the work intensity and improves the work efficiency, which facilitates the on-site verification of transformers;

       3. The current transformer error field tester has a standard voltage transformer equivalent to the same transformation ratio of the current transformer under test. Its accuracy can reach 0.02, which is equivalent to 0.05S current transformer.

The sensor can accurately measure the transformation ratio and no-load error of the current transformer under test. Then combine the test results of impedance and admittance to calculate the error of the transformer;

       4. The current transformer field calibrator adopts the different frequency power supply test close to the power frequency to prevent on-site power frequency electromagnetic radiation and series interference;

       5. The measurement range is wide, which can measure current transformers with standard transformation ratios and non-standard transformation ratios;

       6. The accuracy of the transformer calibrator attached to the tester can be verified by the transformer calibrator calibration device;

       7. The current transformer field calibrator directly converts the field data and judges whether it is qualified or unqualified;

       8. Measuring standard transformation ratio current transformer and measuring non-standard transformation ratio current transformer 1%-120% (S grade) of the regulation point error (angle difference, ratio difference);

       9. Any point error (angle difference, ratio difference) between 1%-200% (S grade) of measuring standard ratio current transformer and measuring non-standard ratio current transformer;

      10. Measure and display the regulation point and the error (angle difference, ratio difference) of the current transformer under the upper limit load and the lower limit load at one time;

      11. One measurement and display of the current transformer's actual regulation point under any load and the error (angle difference, ratio difference) at any point;

      12. Detect the polarity and transformation ratio of known current transformers and non-known current transformers, and can determine the actual current ratio of the non-known current transformers, and can vaguely determine the non-known

Is the secondary current of the current transformer 5A or 1A;

      13. Intelligently judge the status of external wiring, prompt wiring error, transformation ratio, polarity error, etc. Automatically round up the test data and judge whether it is out of tolerance;

      14.320*240 large screen LCD display, all Chinese interface. Simple wiring and operation, easy to carry;

      15. Various measurement data can be stored and printed on site, which is convenient for users to query;

      16. The tester can easily connect to the computer to transmit data through a standard USB interface, and the background management software will process the report and print the certificate according to the national standard;

      17. The case should be made of shock-proof and pressure-proof materials to ensure the safety of on-site operators and equipment.
