| Voltage Transformer On-site Calibrator |
Transformer Calibrator Functions
1. Meet the error detection (angle difference, ratio difference) at 20%-120% of the regulation points for measuring voltage transformers as required by national regulations
2. Complete measurement and display in one go (according to regulations) of the error at regulation points under upper and lower limits of load for voltage transformers (angle difference, ratio difference)
3. Complete measurement and display in one go of the error at regulation points under two groups of actual arbitrary loads for voltage transformers (angle difference, ratio difference)
4. The voltage transformer calibrator detects the transformation ratio and polarity of voltage transformers
5. This on-site voltage transformer calibrator measures the actual secondary load on site
6. The tester can display the test wiring diagram, making it easy for operators to check the wiring
7. The tester intelligently prompts wiring errors, ensuring the safety of the tester and the accuracy of detection
8. The voltage transformer calibrator uses a low-voltage testing principle to actively ensure the safety of operators
9. 320*240 large-screen LCD display, all-Chinese interface. Simple wiring and operation, easy to carry
10. This on-site voltage transformer calibrator can store and print various measurement data for user convenience
11. The voltage transformer calibrator can be optionally equipped with our company's portable rechargeable test power supply for convenient on-site power access
The on-site voltage transformer calibrator, also known as a voltage transformer calibrator or PT transformer calibrator, is a voltage transformer calibration tester designed for voltage transformer verification. It measures the ratio difference and angle difference of voltage transformers according to national standards, can directly measure the transformation ratio, polarity, and secondary DC resistance of voltage transformers, and can measure the actual secondary load of transformers on site. The DGQL-H on-site voltage transformer calibrator is a portable voltage transformer calibration device developed by Dingsheng Electric. It measures the ratio difference and angle difference of voltage transformers according to national standards, can directly measure the transformation ratio, polarity, and secondary DC resistance, and can measure the actual secondary load on site. The DGQL-H on-site voltage transformer calibrator uses high-precision, automatically linearly adjusted DC and AC power supplies, high-speed, high-reliability digital processing modules; high measurement accuracy and stability, and a front-end measurement circuit ensures the accuracy and high stability of the tester's measurements. In addition, the on-site voltage transformer calibrator uses a 320x240 large LCD all-Chinese interface platform technology, with a user-friendly human-machine interface that prompts wiring and operation, and has the function of saving any measurement parameters and printing measurement results.
