Transformer CT Current Transformer Testing Equipment On - Site Calibrator

Introduction

The device is developed with high-end testing technology, large-scale electronic circuit design and accord with national related protocol . It has solved the problem of big working intensity, trivial operation when on site test current transformer, voltage transformer. Meanwhile the product has a reliable performance, and powerful functions.

Features

1. Recursive method to measure current transformer error

2. Test without standard current transformer, Load Box, adjustable control box and primary cable. Using extreme simple wire connection and operation to test,

3. Accuracy 0.05S, measure accurately the turn ratio and load error, Then combined with the impedance and admittance test results to deduce the transformer error.

4. Variable frequency power supply with frequency close to power frequency, which can prevent power frequency electromagnetic radiation and series interference.

5. Wide Measurement range: 5A/5A~25000A/5A or 5A/1A~5000A/1A.

6. Current transformer turn ratio, secondary winding resistance test function.

7. With 800×600 high resolution and large screen LCD, humanized interface

8. Precise software algorithm further improved the measuring accuracy

9. Intelligently judge the external connection status, give tips of errors

10. Auto error rounding function, ultra poor data will be displayed in orange color and in the lower right corner of the window

11. Issue directly field verification conclusion ( pass or super poor)

12. Storage capacity up to 1000 items of field test results.

13. RS232 or USB interface to connect computer and print data certificate.

14. With engineer plastic mold box, shock-proof
