Partial discharge. Part XXIV: The analysis of PD in HVDC equipment
IEEE Electrical Insulation Magazine, 1997 High voltage dc is required in a wide range of consumer, commercial, and military applications. Presently available PD analysis for dc systems can extend far beyond the old-fashioned "not more than 'n' PD pulses per minute over a given magnitude".

Partial discharges characteristics study in XLPE cable insulation with multiple defects [PDF]
Омский научный вестник, 2021 The paper simulates the electric field intensity picture in the cable with one and several defects. Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with

Partial Discharge Behaviour within Two Spherical Cavities in a Dielectric Material [PDF]
, 2011 In high voltage insulation systems, a typical defect that exists is a void cavity. It is known that voids are a common source of partial discharge (PD) activity within an insulation system.
