Figure 28: PD display mode
the current PD peak magnitude is shown in the upper left corner of this graph. The magnitude has to be cali-
brated (see applications notes in section 5.7). The time domain graph in the lower left area can be used to
evaluate single PD events and the reflections of pulses, as detected on medium and high voltage cable insula-
tion systems on a time-based curve (resolution of 100 Msamples/second). The different cursors will help to
determine the exact fault position and to get precise results. In the area on the lower right-hand side, a 3-dimen-
sional PD pattern acquisition can be started and visualised. The phase resolved PD pattern has a resolution of
8 bits x 8 bits with a 16-bit colour depth and allows further interpretation of failures within the insulation system
and its cause. Besides the pattern itself, the related discharge levels, set time, and the number of events is
shown.
