Frequency Conversion Transformer Tester

Product Features:

This testing system can fully meet the various testing requirements of various CTs (including protection, metering, TP, etc.), such as excitation characteristics (volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference, and phase difference. At the same time, the system is also suitable for testing the excitation characteristics, transformation ratio, polarity, and secondary winding resistance of various PT electromagnetic units.

The system can automatically calculate and provide key parameters such as knee voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), residual magnetism coefficient (Kr), saturated and unsaturated inductance, providing comprehensive and accurate data support for CT performance evaluation.

The system strictly follows various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, and can automatically select the corresponding test standards according to the transformer type and level to ensure the accuracy and reliability of the test results.

Based on the advanced low-frequency test principle, the system can easily handle CT tests with knee points up to 40KV or higher, demonstrating strong testing capabilities and wide applicability.

In addition, the testing process is simple and convenient, with one button to complete the CT's direct resistance, excitation, transformation ratio, and polarity tests. Except for load testing, all other CT tests use the same wiring method, greatly improving test efficiency and convenience.

Additional Features:

Intuitive and user-friendly graphical interface: The device is equipped with a 10-inch color large screen with a fully Chinese graphical interface design, which is not only beautiful but also user-friendly. The fully Chinese display makes it easy for users to get started, and the printer function built into the panel allows users to print out curve graphs and test data anytime to meet the needs of immediate viewing and sharing.

Large-capacity data storage: The built-in large-capacity memory can store up to 2000 sets of test data. Even when the device is powered off, the data will not be lost, ensuring the integrity and security of the data.

Convenient data transfer and analysis: After the test is over, users can directly store the data into a USB flash drive for subsequent in-depth data analysis using professional software on a computer. In addition, the software also supports automatically generating WORD reports to make data presentation more standardized and professional.

Intelligent data processing: The device has a knee point automatic calculation function that can intelligently filter and print out key test data. At the same time, the built-in date/time function ensures that each data has an accurate timestamp, facilitating data traceability and management for users.

Lightweight and portable design: The device adopts a single-machine integrated design, with an overall weight of only 8.2Kg, making it lightweight and portable. Whether it is used in the laboratory or for on-site mobile testing, it can easily cope with various situations, bringing great convenience to users.
