摘要： The charge value of a partial discharge pulse in an electrical cable is provided by analyzing the frequency spectrum of the propagated pulse in a spectrum analyzer 21 to generate sets of spectrum signals, each including a magnitude and a frequency of a component of the pulse. A laptop computer has a processor, receives the spectrum signals, and has one or more application computer programs operable to perform the calculations of Equations 2-6, finds the bandwidth and energy of the spectrum signals from which the computer programs derive unknown time domain parameters including the maximum value of the pulse and the time interval of the pulse at half its maximum value. With those parameters, the program reconstructs a time domain signal of the pulse and integrates that signal to provide the charge value of the partial discharge.

摘要： A capacitor component is adapted for capacitive coupling to an electrical power apparatus in which a PD is suspected, such as a shielded power cable; and an impedance transformance device has an input side connected directly to the capacitor component. Together the two components are used as a sensor to pick up and convey PD signals to a PD signal-analyzing system. Although the two components inherently form a classic high-pass RC filter, in accordance with the invention the input impedance at the capacitor side is much greater than the output impedance at the signal-analyzing system side. The effect is to pass much more of the lower frequency components of the PD signal for analysis by the PD signal-analyzing system than if the tranformance device were not included.
