Product Details

Product Introduction

The partial discharge configuration software features real-time waveform display, 1 large peak value display, positioning and other functions. The software can also analyze a specific phase waveform in detail, partial discharge, windows can be enlarged and reduced at will, and frequency spectrum analysis can be performed on the data segment to analyze the frequency spectrum content of the discharge waveform, making discharge waveforms more comparable. The GIS partial discharge detector provides comprehensive statistical analysis of test data, reducing the impact of unstable factors during testing on test results.



Working Principle

The partial discharge test principle is the high-frequency pulse current measurement method, also known as the ERA method. When the test object CA generates partial discharge under the test voltage, the discharge pulse signal is sent to the input unit through the coupling capacitor CA. The pulse signal picked up by the input unit is amplified by a low-noise preamplifier, filtered by the filter amplifier to select the required frequency band, and amplified by the main amplifier to reach the required amplitude. After generating a zero marker pulse, a visible discharge pulse is produced on the elliptical scanning baseline of the oscilloscope screen, and it is also sent to the pulse peak meter to display its peak value.
