1、 YTC2145On-site Tester for Current Transformer combines the functions of measuring current transformer errors using the recursion method and voltage transformer errors using the potential difference method, facilitating on-site verification of metering devices.
2、 On-site verification of current transformers does not require standard currentTransformer Calibrator, current booster, load box, voltage regulator control box, and high-current wires. It uses extremely simple test wiring and operations to achieve current transformer verification, greatly reducing work intensity and improving work efficiency, facilitating on-site transformer verification.
3、 The YTC2145 on-site calibration instrument for current transformers has an internal standard voltage transformer with the same ratio as the tested current transformer, with accuracy up to 0.05 level, accurately measuring the ratio and no-load error of the tested current transformer. Then, combined with the test results of impedance and admittance, the transformer error is calculated.
4、 It uses a power supply with a frequency close to power frequency but different from it for testing, to prevent on-site power frequency electromagnetic radiation and series interference.
5、 Wide measurement range, up to 5A/5A~25000A/5A or 25A/1A~5000A/1A.
6、 It has the function of testing the current transformer ratio and the internal resistance of the secondary winding.
7、 It adopts a 640×480 high-resolution large-screen LCD display, with a user-friendly interface and operation design, and uses a touch screen for auxiliary operation, making operation more convenient and faster.
8、 It uses precise software algorithms to further improve the accuracy of measurement data.
9、 It has intelligent judgment of external wiring conditions, prompting wiring errors, ratio errors, polarity errors, etc.
10、 It automatically rounds the test data and judges whether it exceeds the tolerance. Data exceeding the tolerance is displayed in reverse black, making the data characteristics of the transformer intuitive and clear.
11、 It directly gives the on-site verification conclusion, whether it is qualified or unqualified.
12、 The large-scale memory can store up to 1000 items of on-site test data.
13、 It comes with a printer to print test data on site.
14、 It uses an engineering plastic mold chassis that is shockproof and pressure-resistant, ensuring the safety of on-site operators and equipment safety.
