Current Transformer Calibration Device

I. Product Introduction

High-voltage electrical energy metering 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. To ensure accurate measurement, it is imperative to comply with...SD109 "Electric Energy Metering Equipment Inspection Code" and DL/T448-2000 "Technical Management Code for Electric Energy Metering Equipment" are undergoing inspections.

Our company'sThe HCCT-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 complicated operations during on-site calibration of current and voltage transformers. The product is also reliable in performance and boasts powerful functions.

II. Features

The HCCT-H Current Transformer Field Calibration Instrument features the function of measuring current transformer errors using the recursive method, facilitating on-site calibration of measurement devices.

2. Field calibration of current transformers requires no standard current transformers, current boosters, load boxes, voltage control boxes, or large current conductors.Extreme.To realize the calibration of current transformers for simple test wiring and operation.Extreme.Significant reduction in work intensity and enhancement of work efficiency, facilitating on-site field calibration of transformers.

The HCCT-H current transformer field calibration instrument features an internal standard voltage transformer with the same transformation ratio as the measured current transformer. Its accuracy reaches 0.05 class, allowing for precise measurement of the transformer ratio and no-load error of the measured current transformer. Then, by combining the results of impedance and admittance tests, the transformer's error can be calculated.

4. Utilize power source tests with frequencies close to the industrial frequency to prevent on-site electromagnetic radiation at industrial frequencies 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.
