2 Standards Followed
Compliant with "Regulations for Handover and Preventive Tests of Power Equipment"
3 Basic Performance Parameters of the Product
3.1 Instrument Features
1. The YTC2135 Voltage Transformer Error Tester integrates both the low-calibration-high method and the potential difference method for measuring voltage transformer errors, facilitating on-site verification of metering devices.
2. On-site verification of voltage transformers does not require standard voltage transformers, boosters, load boxes, or voltage regulating control boxes. It uses extremely simple test wiring and operation to achieve verification of electromagnetic voltage transformers, greatly reducing work intensity and improving work efficiency, making on-site verification of transformers convenient.
3. The YTC2135 Voltage Transformer Error Tester has a built-in standard voltage transformer with the same transformation ratio as the tested voltage transformer, with an accuracy of 0.02 class. It accurately measures the transformation ratio and no-load error of the tested voltage transformer, and then calculates the transformer error based on the test results of impedance and admittance.
4. Wide measurement range.
5. Has functions for testing voltage transformer ratio, DC internal resistance, and voltage load box.
6. Has testing function for dual-winding voltage transformers, equipped with two load boxes.
7. Uses a 640×480 high-resolution large-screen LCD display with user-friendly interface and operation design, and touch screen auxiliary operation for more convenient and faster operation.
8. Uses precise software algorithms to further improve the accuracy of measurement data.
9. Has intelligent judgment of external wiring conditions, prompting wiring errors, ratio errors, polarity errors, etc.
10. Automatically rounds test data and determines whether it exceeds tolerance. Out-of-tolerance data is displayed in reverse black, making the data characteristics of the transformer intuitive and clear.
11. Directly issues on-site verification conclusions, either qualified or unqualified.
12. Large-scale memory can store up to 1000 sets of on-site test data.
13. Equipped with a printer, can print test data on-site.
14. Uses engineering plastic mold chassis, shockproof and pressure-resistant, ensuring the safety of operators and equipment during high-voltage tests on site.
