The error tester of current transformer has the measuring error of current transformer by the recursive method, which is convenient for the on-site verification of measuring device.
The on-site verification of current transformer does not require standard transformer, current booster, load box, voltage control box and high current wire. It uses very simple test wiring and operation to realize the verification of current transformer, greatly reduces the work intensity and improves the work efficiency, and is convenient for on-site verification of current transformer.
Product Features: The on-site current transformer tester employs a recursive method to measure transformer errors, facilitating on-site calibration of metering devices.
Field calibration of current transformers eliminates the need for standard transformers, current boosters, load boxes, voltage regulation control boxes, or high-current conductors. By employing simplified test wiring and operational procedures, the calibration process significantly reduces labor intensity and enhances efficiency, facilitating on-site transformer calibration operations.
The tester achieves an accuracy class of 0.05, enabling precise measurement of the ratio error of the tested current transformer. By combining the test results of impedance and admittance, the error of the transformer can be calculated.
The testing employs an inverter power supply with near power frequency to mitigate both on-site power frequency electromagnetic radiation and series interference.
Current transformers feature a wide error measurement range, spanning from 5A to 25000A/5A or 5A/1A to 5000A/1A.
It features current transformer and voltage transformer with variable ratio, as well as secondary winding internal resistance testing capability.
The device features an 800×480 high-resolution large-screen LCD display with a user-friendly interface and intuitive operation design. Touchscreen-assisted controls enhance operational convenience and speed.
By employing precise software algorithms, the accuracy of measurement data is further enhanced.
It features intelligent judgment of external wiring conditions, providing alerts for wiring errors, incorrect transformer ratios, and polarity errors.
The system automatically divides test data into fractions and checks for deviations. Excess data is highlighted with a black background, providing a clear and intuitive view of the transformer's operational characteristics.
Directly issue on-site verification conclusions, indicating compliance or non-compliance.
The large-scale storage device can store up to 1000 pieces of field test data.
Includes a printer for on-site printing of test data.
