Wave Recorder

Wave recorder is a transient signal recording instrument which is developed for the application of power system. The internal software of the instrument preset the test template for generator debugging, the user can easily complete the generator short circuit characteristic test, no-load characteristic test, excitation system disturbance test, excitation system 10% step test, demagnetization constant measurement, self-quasi-synchronization device check, unit load rejection record and so on.

The instrument has rich software components to enable users to carry out graphic analysis, combined operation, effective value calculation, AC power calculation, three-phase symmetry analysis, spectrum analysis, harmonic analysis, curve correlation analysis through software components. Graphic editing and phasor drawing operations. Test data and analysis results can be generated WORD/EXCEL form , it also can be generated by software JPG picture in order to facilitate the user to conduct in-depth analysis and processing of the test results.

The instrument has 12 analog input ,12 active switch input and 3 open output signals. The maximum sampling frequency can reach 100 KHZ, which can basically meet the transient signal recording requirements of various tests in power system. All simulation channels are isolated from each other to avoid the failure of the system under test due to the connection problem of different potential points in the test.

The functions of the instrument include data acquisition, data compression storage, waveform analysis and statistics, graphics drawing tools, spectrum analysis tools, waveform combination operation tools, harmonic analysis, effective value calculation, power calculation, three-phase symmetry analysis, phasor diagram tools and so on
