■ Product Overview
Vspd-200/200a PARTIAL discharge tester can be used together with uHF sensors, TEV sensors, acoustic and electrical combination sensors, ultrasonic sensors and broadband current transformers (HFCT) online detection of partial discharge transformers, high voltage switchgear, GIS, cable connectors and other high voltage equipment. Easy to carry, fast measurement, strong anti-interference ability, easy to use on site.
Its configuration software with real-time waveform figure, large peak display, positioning, and other functions, the software can also be a detailed survey analysis phase waveform, window zoom in and out at will, also can undertake spectrum analysis of this data, analysis of the discharge waveform frequency content, more comparability between the discharge waveform, comprehensive statistical analysis of test data, Reduce the influence of non-stability factors on test results.
The instrument adopts automatic or manual record to save test data and transient discharge waveform, providing reference for later data analysis.
Vspd-200 has two measuring channels, and VSPD-200A has four measuring channels.
