Detailed Introduction of Batch Testing Device for Medium Voltage Transformers

The batch testing device for medium voltage transformers is an automated equipment used for performance testing and maintenance of current transformers (CT) and voltage transformers (PT) in power systems. It has functions such as high-precision, multi parameter synchronous testing, automated operation, data storage and processing, and can efficiently complete the calibration tasks of batch transformers. The following provides a detailed introduction from four aspects: core functions, technical features, application scenarios, and typical products:

1. Core functions

① Multi parameter synchronous detection: It can simultaneously measure key parameters such as transformer ratio, error, phase angle difference, polarity, and volt ampere characteristic curve of transformers, support error data measurement under light load conditions, and meet the calibration needs of different types of transformers.

② Automated operation process: Fully automated testing is achieved through computers or dedicated controllers, including automatic voltage/current boosting, data acquisition, error calculation, result judgment, etc., without the need for manual intervention, greatly improving work efficiency. The fully automatic transformer calibration platform can automatically complete the measurement, data acquisition, error calculation, result judgment and other processes of the transformer.

③ Data storage and processing: Built in large capacity storage, capable of storing a large amount of test data, supporting functions such as data export, editing, printing, etc., for easy subsequent analysis and management. Some devices also have upper computer software that can display error curves and achieve virtual instrument opening functions.

2. Technical features

① High precision measurement: Using high-precision standard transformers, digital signal processing technology, and off frequency power supply testing, effectively avoiding on-site power frequency electromagnetic radiation and series interference, ensuring detection stability in complex environments. 

② Multi channel batch testing: Supports multi-channel synchronous testing, which can simultaneously detect multiple transformers, significantly improving batch testing efficiency. Some devices also have the function of automatically switching load boxes, reducing manual operation and lowering the risk of operational errors.

③ Portability and ease of use: The device is designed to be compact, lightweight, and easy to carry to the site for testing. At the same time, it adopts a fully Chinese operating interface, large screen LCD display, and large font display of measurement results, making it convenient for users to observe and operate.

3. Application scenarios

① Regular calibration of power systems: used for the regular calibration and calibration of medium voltage transformers in substations, power plants, power supply companies, and other places to ensure the accuracy and reliability of transformers and ensure the safe and stable operation of the power system.

② Equipment maintenance in industrial enterprises: Electrical equipment in various industrial enterprises needs to be measured and protected using transformers. Batch testing devices can be used for internal transformer testing and maintenance to ensure the normal operation of production equipment.
