Current Transformer Comprehensive Tester

Product Introduction

High-voltage electric energy measurement devices at power plants and substation, as well as those for a large number of end-users, are crucial to the interests of power generation, transmission, supply, and users alike. To ensure accurate measurement, it is mandatory to followSD109 "Electric Power Metering Equipment Inspection Procedure" and DL/T448-2000 "Electric Power Metering Equipment Technical Management Procedure" undergo inspections.

Our company'sThe EDCT-H Current Transformer Field Calibration Instrument is developed with advanced testing technology, large-scale electronic circuit design, and in compliance with national regulations. It addresses the issues of high workload and complex operations during on-site calibration of current and voltage transformers, while offering reliable performance and powerful functions.

II. Features

The EDCT-H Current Transformer Field Calibration Instrument features a recursive method for measuring current transformer errors, facilitating on-site calibration of measurement devices.

2. Field calibration of current transformers does not require standard current transformers, current boosters, load boxes, voltage regulation control boxes, or large current conductors.Extreme.For the simple testing of wiring and operation to calibrate current transformers.Extreme.Significantly reduced workload and increased efficiency, facilitating on-site transformer calibration operations.

The EDCT-H Current Transformer Field Calibration Instrument is equipped with a standard voltage transformer that has the same transformation ratio as the measured current transformer. Its accuracy can reach 0.05 class, accurately measuring the transformation ratio and no-load error of the measured current transformer. Then, by combining the test results of impedance and admittance, the transformer's error can be calculated.

4. Utilize power source tests with frequencies close to industrial power frequency to prevent electromagnetic radiation and series interference on-site.

5. Wide measurement range, up to5A/5A to 31500A/5A or 5A/1A to 6300A/1A。

6. Features current transformer ratio and secondary winding resistance testing functions.

7. Adopted800×600 High-Resolution TFT Color LCD Touch Display with Large ScreenThe interface and operational design are user-friendly, featuring touch screen assistance to make operations more convenient and swift.

8. Utilizing precise software algorithms, the accuracy of the measured data has been further enhanced.

9. Features intelligent judgment of external connection status, alerting for wiring errors, ratio discrepancies,Extreme.Sexual misconduct.

10. The system automatically rounds test data and identifies any deviations. Deviant data is displayed in orange, and an alert appears in the bottom-right corner of the window, providing a clear and intuitive understanding of the transformer's data characteristics.

11、Domestically first to offer a test solution that simultaneously measures the ratio of voltage transformers.Extreme.Sexual function。

12. Directly issue on-site verification conclusions, passing or failing.

13. The large-scale storage can hold up to 1,000 field test data entries.

14. Connect the computer to print data certificates using RS232 or USB interfaces.

15. The engineering plastic mold casing is designed for shock and pressure resistance, ensuring the safety of both the on-site operators and the equipment.
