Description
Frequency Response Analyzer HYRZ-903 is an important electrical equipment, its safe and reliable running is extremely important to the power system. The Power Transformer comprehensive parameter tester is a high-precision instrument independently developed by our company specifically for the measurement of transformer sweep frequency response, short circuit impedance, Zero sequence impedance, no-load and load loss parameters of the power transformer (three-phase or single-phase) in the factory test, acceptance test and maintenance routine test. It uses the ARM processor as the core control for sampling, processing and output. Its main features are colorful touch screen display and simple operation. The tester equipped with a high-speed thermal printer, and a storage function designed to facilitate data storage and printing. The tester integrated USB port for PC connection. The PC software can control the tester for testing and data upload VIA this USB port. PC software can convert the saved results or upload results to Word or Excel report. The tester is small size, lightweight and easy to carry. It is very convenient to use in the field, which greatly reduces the labor intensity of the test personnel, and the work efficiency is improved.
The tester can be used to test all kinds of power transformers with different voltage regulator configuration. At the same time, this product can also be used for generator rotor AC impedance test and harmonic test (PC available).
