So-called ‘time-of-flight’ (TOF) measurements have been employed for locating PD sources within GIS for over 20 years. Portable digital sampling oscilloscopes have now become available for reasonable cost whose input rise-times, bandwidths, and s

Top quality high voltage pre-test of solid insulating material requires long test intervals because the initiation of partial discharge (PD) in voids not only demands a sufficiently high electric field, but also the availability of a start electron.
