In the last few years computer controlled digital recorders have almost completely replaced analog oscilloscopes in high voltage (hv) test laboratories, as they enable automated hv testing and record processing. However, as yet, no generally accepted software or algorithm exists for the data processing of hv impulses and of the step responses of hv dividers.
The objective of the intercomparison is to gather a sound and updated body of information for the establishment of a future standardized software in hv impulse tests. A set of data files on several typical hv impulses and step responses, both synthetic and actually measured, will be sent to each participating laboratory to compute with its individual software the prescribed parameters.
The work is in progress.
