Current Transformer Calibration Device

I. Product Introduction

High-voltage power measurement devices at power plants and sub-stations, 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 toSD109 "Electric Power Metering Equipment Inspection Code" and DL/T448-2000 "Technical Management Code for Electric Power Metering Equipment" are undergoing inspection.

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

II. Features

The EDCT-H Current Transformer Field Calibration Instrument features the capability to measure current transformer errors using the recursive method, facilitating on-site calibration work for metrological equipment.

2. Field calibration of current transformers requires no standard current transformers, current boosters, load boxes, voltage regulation control boxes, or large current conductors, utilizingExtreme.To facilitate the calibration of current transformers for simple test wiring and operation.Extreme.Significant reductions in workload and improvements in efficiency have made it easier to conduct on-site transformer calibration work.

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 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 error of the transformer is calculated.

4. Utilize near-power-frequency heterodyne power source testing to prevent on-site power-frequency electromagnetic radiation and series interference.

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