Current Transformer Field Calibration Instrument

I. Product Overview

High-voltage power 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 the users themselves. To ensure accurate measurement, it is imperative to adhere to...SD109 "Electric Energy Measurement Equipment Inspection Procedure" and DL/T448-2000 "Electric Energy Measurement Equipment Technical Management Procedure" are being inspected.

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 measuring 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.To achieve the calibration of current transformers for simple test wiring and operation.Extreme.Significantly reduced work intensity and increased efficiency, facilitating on-site field calibration of transformers.

The EDCT-H Current Transformer Field Calibration Instrument is equipped with a standard voltage transformer of the same transformation ratio as the measured current transformer, achieving an accuracy of up to 0.05 class. It accurately measures 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 is calculated.

4. Utilizing near-frequency power supply testing to prevent on-site electromagnetic radiation at power frequency and series interference.

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 for enhanced ease and speed of operation.

8. With the adoption of precise software algorithms, the accuracy of data measurement has been further enhanced.

9. Features intelligent judgment of external wiring conditions, alerting to wiring errors, ratio discrepancies,Extreme.Sexual misconduct.

10. Automatically rounds test data and determines if it exceeds the allowable deviation. Data that exceeds the limit is displayed in orange, with an alert shown in the bottom right corner of the window, providing a clear and intuitive understanding of the transformer's data characteristics.

11、Domestically first to test the ratio and voltage transformer simultaneouslyExtreme.Sexual function。

12. Issue on-site calibration findings directly, indicating as qualified or exceeding specifications.

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

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

15. The engineering plastic mold case is designed with vibration and pressure resistance to ensure the safety of both the on-site operators and the equipment.
