Product Introduction：XSN-HDL-01The on-site current transformer calibrator has a standard voltage transformer equivalent to the current transformer under test with an accuracy of level 0.05, and a standard current transformer with the same ratio with an accuracy of level 0.05 is built into the instrument, which can accurately measure the current transformer ratio and no-load error under test. Then the error of the transformer is calculated based on the measurement results of impedance and admittance.
Product features:
1. Use different frequency power supply close to power frequency to test to prevent field power frequency electromagnetic radiation and series interference;
2, with current transformer ratio polarity, secondary winding internal resistance, DC resistance test function;
3, 8 inch 1024×768 high resolution large screen TFT color LCD touch display, with user-friendly interface and operation design, the use of touch screen auxiliary operation, make the operation more convenient and fast;
4. Automatically adjust the test data and judge whether it is out of tolerance. The out of tolerance data is displayed in orange and in the lower right corner of the window.
5, at the same time can test the voltage transformer ratio and polarity function;
6. The instrument can test the transformer's change ratio blindly, and give the calculated change ratio after the test result;
7, large-scale memory can store field test data up to 1000;
8. Use RS232 or USB interface to connect computer to print data;
9, the built-in battery charging time is about 12-24 hours, after full can work for more than 12 hours.
