Features and Advantages
1. The host has 4 partial discharge inputs and 1 voltage input, which can monitor the relationship between each test voltage and partial discharge in real time. It provides Q (V), Q (t)&V (t) spectra, which can intuitively record and display the discharge starting voltage and extinguishing voltage of the test sample.
2. The multi host mode enables simultaneous detection of up to 4 voltage channels and 16 partial discharges, meeting the current transformer partial discharge testing requirements of 9 channels and up to 16 channels simultaneously.
3. Multiple testing options are available for AC partial discharge and DC partial discharge, suitable for AC partial discharge testing analysis, DC partial discharge testing analysis, partial discharge point positioning analysis, etc.
4. The tester has the most flexible analysis tool among digital partial discharge detectors. Extended functions include signal spectrum analysis, pulse analysis, external pulse identification, noise suppression, 3D rotatable PRPS and PRPD analysis, and discharge mode feature identification.
5. The rich hardware and software noise suppression modules increase the anti-interference ability of the equipment on site. The noise suppression methods that meet IEC standards include time window method, polarity distribution, pulse smoothing method, and frequency selection method, which further enhance the on-site interference suppression capability.
6. Measurement data can be automatically recorded, and partial discharge data, voltage data, and trend records such as Q (V), Q (t)&V (t) can be automatically completed.
7. Experimental data, information, trends, graphs, etc. can be flexibly output in the form of custom data tables (Microsoft of ice Word), and the company logo can be easily embedded.
