Transformer winding deformation tester

As an important electrical equipment, the safe and reliable operation of power transformers is extremely important for the power system. The transformer comprehensive characteristic tester is a self-developed device by our company specifically designed for winding deformation during factory, fault, and handover tests of power transformers (three-phase or single-phase). It uses an ARM processor as the core control for sampling, processing, and output. Its main characteristics are color touch screen display, Chinese menu prompts, simple operation, equipped with a high-speed thermal printer, designed with storage function, convenient for data storage and printing; Equipped with data management software, the saved data is transferred to the computer (upper computer) through USB for multiple operations such as saving, printing, and clearing, or directly tested through the upper computer. The saved file format is Word or Excel file format. The instrument is small in size, light in weight, easy to carry, and extremely convenient for on-site use, greatly reducing the labor intensity of the testing personnel and improving work efficiency.

Main Test Items and Functions

1. Sweep frequency method winding deformation test based on different standards;

2. It can measure the phase frequency curve and amplitude frequency curve of each winding of the transformer;

3. The phase and amplitude of the transformer winding can be tested cyclically at a fixed frequency;

4. Analyze the amplitude frequency curve of transformers based on DLT911-2016;

5. Built in non power-off memory, capable of storing 40 sets of winding deformations;
