The advantages and functions of the variable frequency transformer comprehensive tester are mainly reflected in the following aspects:
1. Fully functional:
The frequency conversion transformer comprehensive tester can meet various testing needs for CT (such as protection, metering, TP) excitation characteristics (i.e. volt ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference.
At the same time, the tester can also be used for testing the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference, and angle difference of various PT electromagnetic units, achieving comprehensive performance evaluation of transformers.
2. Intelligent automatic testing:
The instrument can automatically provide CT and PT parameters such as inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument safety factor (FS), quadratic time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance.
During the experiment, only the test voltage/current values need to be set without setting the step size. The equipment can automatically boost/boost the current and quickly display the transformer's volt ampere characteristic curve, transformation ratio, polarity, and other experimental results. It supports data storage and on-site printing, eliminating the tedious labor of manual voltage regulation, manual recording, and curve drawing.
3. High precision and stability:
The comprehensive tester for variable frequency transformers adopts high-performance DSP and ARM technology, as well as advanced manufacturing processes, to ensure stable and reliable product performance, complete functions, high degree of automation, and high testing efficiency.
The tester can accurately measure the ratio difference and angle difference, with an allowable error of ± 0.1% for ratio difference and ± 5 minutes for angle difference. It can perform on-site testing of 0.2S-level current transformers, with a ratio measurement range of 1-30000.
4. Meet national standards:
The testing of the variable frequency transformer comprehensive tester can meet various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically select which standard to test according to the type and level of transformer to ensure the accuracy and reliability of the test results.
5. Convenient data processing and report generation:
The tester supports data saving and on-site printing functions, and can automatically filter and print typical report usage data, making it very suitable for on-site data comparison.
At the same time, the tester is also equipped with a USB interface, which facilitates the connection of new laptops for data transfer and uploading of test data, as well as editing, saving or printing.
6. Portability and ease of use:
The comprehensive tester for variable frequency transformers is designed to be compact, small in size, and lightweight, making it easy to carry and use on site.
Adopting a user-friendly interface design such as a rotating mouse and a large LCD display, making the operation more convenient and intuitive.
