Section Two: Features

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

2. Field calibration of current transformers requires no standard current transformer, current booster, load box, voltage regulator control box, or large current conductors.Extreme.To achieve the calibration of current transformers for simple test wiring and operation.Extreme.Significantly reduced work intensity and improved efficiency, facilitating on-site transformer calibration operations.

3. The HCCT-H Current Transformer Field Calibration Instrument is equipped with a standard voltage transformer of the same transformation ratio as the measured current transformer. Its accuracy can reach 0.05 grade, 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 error of the transformer can be calculated.

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

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

6. Features testing functionality for current transformer ratio and secondary winding resistance.
