Product Overview

The waveform recorder is a transient signal recording instrument developed for power system applications. The internal software of the instrument is pre-set with a test template for generator debugging, allowing users to easily complete the generator through the recorderThree phase short-circuit characteristic curve, no-load characteristic curve, load rejection test, self synchronization verification test, excitation system disturbance test, excitation system frequency and voltage characteristic test, excitation system demagnetization time constant measurement, generator phase advance test, generator rotor AC impedance test, power analysis test, excitation systemProcess records of PSS test, motor start-up test, transformer impact test, power system fault diagnosis, etc.

The instrument has rich software components that allow users to perform graphic analysis, combinatorial operations, effective value calculation, AC power calculation, three-phase symmetry analysis, spectrum analysis, harmonic analysis, curve correlation analysis, graphic editing, and phasor diagram drawing through software components. Experimental data and analysis results can be generatedThe test report can be in WORD/EXCEL format, and JPG images can also be generated and exported through software to facilitate users' in-depth analysis and processing of the test results.

The instrument has12 analog inputs, 12 active switch inputs, and 3 output signals, with a sampling frequency of up to 100KHZ, can basically meet the transient signal recording requirements of various tests in power systems. And all simulated channels are isolated from each other to avoid connection problems between different potential points during the experiment, which may cause faults in the tested system.
