1、 YTC2145On-site Tester for Current Transformers combines the functions of measuring current transformer errors using the recursive 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 verification of current transformers, greatly reducing work intensity and improving work efficiency, facilitating on-site verification of transformers.
3、 The YTC2145 on-site calibration instrument for current transformers has a built-in standard voltage transformer with the same ratio as the tested current transformer, with an accuracy of 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 error of the transformer 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 ratio of current transformers and the internal resistance of secondary windings.
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 provides on-site verification conclusions, either qualified or unqualified.
12、 The large-scale memory can store up to 1000 sets of on-site test data.
13、 It comes with a printer to print test data on site.
14、 It adopts an engineering plastic mold chassis that is shockproof and pressure-resistant, ensuring the safety of on-site operators and equipment safety.
