Functions of Transformer Calibrator

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) 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 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 adopts the small voltage test principle to actively ensure the safety of operators
9. 320*240 large-screen LCD display, full 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 on-site use, facilitating power access on site

 

The on-site voltage transformer calibrator, also known as voltage transformer calibrator or PT transformer calibrator, is a voltage transformer calibration tester designed for voltage transformer verification.
The voltage transformer calibrator measures the ratio difference and angle difference of voltage transformers according to national standards. It can directly measure the transformation ratio, polarity, and secondary DC resistance of voltage transformers. The on-site voltage transformer calibrator can measure the actual secondary load of transformers on site.

DGQL-H on-site voltage transformer calibrator is a portable device developed by Dingsheng Electric for voltage transformer verification. It measures the ratio difference and angle difference of voltage transformers according to national standards, and can directly measure the transformation ratio, polarity, and secondary DC resistance.
It can measure the actual secondary load of transformers on site. The DGQL-H on-site voltage transformer calibrator uses high-precision, automatically linearly adjusted DC and AC power supplies, and high-speed, high-reliability digital processing modules. With high measurement accuracy and stability,
the front-end measurement circuit ensures the accuracy and high stability of the tester. In addition, the on-site voltage transformer calibrator adopts a 320x240 large LCD full Chinese interface platform technology, featuring a user-friendly interface that prompts wiring and operation,
and has the function of saving any measurement parameters and printing measurement results.
