Transformer Calibration Device

The primary function of the transformer calibrator is to test the technical performance of voltage and current transformers used in field applications or laboratory settings. To achieve this, the transformer calibrator must be integrated with related equipment to form a complete transformer calibration system. Due to the close technical relationship between the performance indicators of the transformer calibrator and the associated equipment, a basic understanding of the transformer calibration system is essential for accurately studying and comprehending the overall concept of the transformer calibrator.

China's transformer testers can be roughly divided into three generations:The.One-Generation Electrical TesterThe system is cumbersome to operate, with complex wiring.No Chinese content provided..The second-generation calibrator utilizes more advanced electronic circuits, offering greater convenience than its predecessor. However, it requires manual switching of range positions during measurement, and displays limited information during testing.No Chinese content provided..The third-generation verifiers mostly utilize single-chip microcontrollers, enhancing the intelligence of the instruments. Some models feature computer communication interfaces, boosting office automation levels.

Utilizing a microcontroller for measurement, control, and display functions.

The computer interface enhances office automation and reduces manual labor intensity.

With a large screen display, offering a user-friendly interface and rich measurement information.

④ Auto-measurement of transformer current and voltage loads, with automatic switching capability.

⑸ Equipped with robust error capture measures, capable of promptly notifying users of error information.

Our instrument can reach Level 2 accuracy. Currently, most calibration meters on the market use a 90° phase shift method based on resistance and capacitance for data measurement. This method is susceptible to environmental temperature and power frequency fluctuations. Any changes in these conditions can significantly affect the measured data.
