TWPD-2H-H Digital Partial Discharge Tester
Scope of application
Suitable for partial discharge detection of transformers, generators, transformers, bushings, GIS, capacitors, CVTs, power cables, switches and other high-voltage electrical equipment of various voltage levels and capacities.
Performance characteristics
(1) Partial discharge detection: partial discharge detection of high-voltage electrical equipment, 4 channels of independent data acquisition (non-channel conversion), synchronous signal sampling, 4 windows to display the partial discharge measurement results separately;
(2) Provide multiple anti-jamming measures in complex scenes: unique antenna noise gating, signal polarity discrimination, partial discharge intelligent identification, dynamic anti-jamming, digital-analog hybrid filtering and other anti-jamming functions;
(3) Multiple analysis functions: phase analysis, fingerprint map, frequency spectrum analysis, 3D map and 2D map analysis;
(4) Automatically generate test reports: automatically or manually record and save test data and transient discharge waveforms, generate test reports, and provide later data analysis references;
(5) Display screen: The display screen is a high-resolution touch screen, which is convenient for on-site operation and use;
(6) Portable mobile: suitable for mobile use in complex environments;
