An extension of the chromatic approach [1] for analysing Partial Discharge (PD) signals is described. This involves a different pre-processing approach and the use of extended chromatic maps based upon the signal amplitude as well as phase angle domain. Examples are presented of this approach for quantifying additional features of real PD signals to discriminate between different PD conditions.
