XSN-HDL-02Current transformer field calibrator

Product introduction：Xsn-hdl-02 current transformer field calibrator has been developed according to site requirements. It can satisfy the user to measure the error (ratio difference, Angle difference) of current transformer. The features of high precision, good stability, small volume and light weight greatly facilitate users.

Product features:

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

2, the current transformer without the standard current transformer, inverter, load cases, regulating control box and high-current conductor, using a very simple test wiring and realization of current transformer test operation, greatly reduce the working intensity and improves the work efficiency, convenient field in transformer field verification work;

3, the current transformer error field tester has a standard voltage transformer equivalent to the current transformer under test, its accuracy can reach 0.02, equivalent to 0.05s current transformer, accurate measurement of the measured current transformer ratio and no-load error. Then the measurement results of impedance and admittance are used to calculate the error of the transformer.

4, adopt different frequency power supply close to power frequency test, prevent field power frequency electromagnetic radiation and series interference;

5, wide measuring range, can measure both standard variable ratio current transformer, and non-standard variable ratio current transformer;

6. The accuracy of the instrument attached with the transformer calibrator can be verified by the transformer calibrator inspection device;

7. Directly integrate the field data and judge qualified or unqualified;

8, measuring standard variable ratio current transformer and measuring non-standard variable ratio current transformer 1%-120% (S class) of the procedure point error (Angle difference, ratio difference);

9, measurement standard variable ratio current transformer and measurement of non-standard variable ratio current transformer 1%-200% (S level) of any point error (Angle difference, ratio difference);

10. Measure and display the error (Angle difference, ratio difference) of the regulation point and any point under the upper and lower load of the ct at one time;

11. Measure and display the error (Angle difference and ratio difference) of the current transformer at any point under any actual load;

12. Detect the polarity and change ratio of the known current transformer and the unknown current transformer, and judge the actual current ratio of the unknown current transformer, and judge vaguely whether the secondary current of the unknown current transformer is 5A or 1A;

13, intelligent judgment of external wiring condition, prompt wiring error, ratio, polarity error, etc. Automatic integration of test data, and judge whether out of tolerance;

14, 320*240 large LCD display, full Chinese interface. Wiring, simple operation, easy to carry;

15. It can store and print all kinds of measurement data on site, which is convenient for users to inquire;

16, the instrument through the standard USB interface convenient connection with the computer data transmission, background management software for report processing and print certificates according to the national standard;

17. The chassis shall be shockproof and pressure-proof material to ensure the safety of operators on site and equipment.
