Calibration of Partial Discharge Detectors for Pulse-Height Distribution Analysis
Abobakr Sultan Ahmed, Asser A. Zaky · IEEE Transactions on Electrical Insulation · 1979
The effect of the calibration-pulse fall times, ranging from 0.52-56 μs, on the response of partial-discharge detectors using a multichannel analyser has been investigated. Although the equalization of fall/rise time ratio results in a single peak distribution, the latter is sensitive to small variations in this ratio. It is shown that a single peak, single-spectrum, can be obtained for ratios of the order of 50.
