Product Features
1. PD detection: PD detection of high-voltage electrical equipment, 4-channel independent data acquisition (non channel conversion), synchronous signal sampling, 4 windows display PD measurement results separately.
2. Provide a variety of anti-interference measures in the complex site: unique antenna noise control, signal polarity discrimination, local amplifier intelligent recognition, dynamic anti-interference, digital analog hybrid filtering and other anti-interference functions. Various anti-interference measures can be flexibly combined and applied, which can effectively reduce the impact of interference on the measurement results and facilitate accurate measurement in the complex environment.
3. Multiple analysis functions: phase analysis, intelligent identification and spectrum analysis, The software can also examine and analyze a phase waveform in detail, enlarge and reduce the window at will, analyze the frequency spectrum of the data in this section, analyze the frequency spectrum content of the discharge waveform, make the discharge waveform more comparable, comprehensively analyze the test data, and reduce the influence of unstable factors on the test results.
4. PD intelligent recognition function can automatically identify interference signal and PD signal under specific conditions and remove interference.
5. Electro acoustic synchronization completes the fault location of AC and DC partial discharge.
6. It can capture and locate the special or random waveform in a single time, and can capture and locate the discontinuous or irregular discharge signal in a single time.
7. Expand the ultrasonic signal waveform to locate accurately, reduce the impact of the ultrasonic wave process on the positioning accuracy. The ultrasonic signal is transmitted by optical fiber, which has strong anti-interference ability, and the transmission distance is more than 500 meters.
8. Internal and external synchronization can be selected at will, with zero mark indication and phase resolution function.
9. Gain range: each channel is adjusted separately, and the waveform display can be adjusted smoothly at any time without affecting the measurement results.
10. Open window in any phase, single window or double window, open freely within 360 degrees. It can monitor the test voltage while detecting the partial discharge.
11. The basic characteristic parameters of PD signal, such as amplitude, phase and frequency, are analyzed.
12. All the collected data and user operation results can be recorded to the hard disk automatically at any time. After recording, playback can be performed as required to reproduce the current partial discharge test discharge waveform and discharge change. The recording can be played back repeatedly, and the discharge details can be observed at any time, which is convenient for analysis and diagnosis of difficult problems.
