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： Data acquisition systems and methods for acquiring test data associated with standard insulated power cables and/or power equipment such as switchgears, transformers, electric motors, etc are disclosed. The test data may then be subsequently analyzed for defects, such as the presence of faults, discharges (e.g., PD, coronas, arcing, etc.). The systems may store the acquired test data on removable, non volatile memory, such as Flash memory. The removable memory may be retrieved by an un-skilled technician periodically and returned to a lab or other test facility for subsequent analysis by highly trained analysts.
