Current Transformer Analyzer

One,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"Code of Practice for the Inspection of Electric Energy Measurement Devices"DL/T448-2000The "Technical Management Code for Electric Energy Measurement Equipment" is undergoing inspection.

Our company'sEDHL—IType Current Transformer(The Error Analysis Tester 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 for on-site calibration of current and voltage transformers, while offering reliable performance and powerful functions.

II. Features

1、 EDHL—IType Current Transformer(The error analysis tester combines the functions of measuring current transformer errors using the recursive method and measuring voltage transformer errors using the potential difference method, facilitating on-site calibration of measurement devices.

2、 On-site calibration of current transformers requires no standard current transformers, current transformers, load boxes, voltage regulator boxes, or large current conductors, utilizingNo Chinese content provided for translation..To achieve the calibration of current transformers for simple test wiring and operation.Extreme.Significant reductions in work intensity and improvements in efficiency have been achieved, facilitating on-site transformer calibration work.

3、 EDHL—IType Current Transformer(Error Analysis) The tester is equipped with a standard voltage transformer of the same transformation ratio as the measured current transformer, achieving high accuracy.0.05Accurately measures the transformation ratio and no-load error of the measured current transformer. Then, combined with the test results of impedance and admittance, calculates the error of the transformer.

4、 Utilizing near-frequency power source tests to prevent on-site electromagnetic radiation from industrial frequency and series interference.
