Partial discharge. II. Detection sensitivity

For pt.I see ibid., vol.6, no.4, p.33-9 (1990). Options for detecting and characterizing the signal generated by a partial discharge (PD) within a test piece or test configuration are examined. Important parameters considered include minimum detectable signal (PD sensitivity), circuit time constants that limit PD waveform characterization (where this may be desirable), and general applicability of the detection scheme. In general, it is found that detection schemes that are most sensitive tend to be somewhat application specific, whereas detection schemes that are of general applicability tend to sacrifice some sensitivity.<
