Time-Frequency Analysis of Partial Discharge Current Pulses in Different Gas Environment under Lightning Impulse

open access: yesMeasurement Science Review, 2020
This paper deals with a time-frequency analysis of the measured partial discharge (PD) currents in different insulation gases. These gas environments consist of a pure SF6 (sulphur-hexafluoride) and sulphur-hexafluoride and nitrogen (1 % SF6 + 99 % N2 ...

Partial Discharge Behaviour within Two Spherical Cavities in a Dielectric Material [PDF]

open access: yes, 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.

Partial discharges characteristics study in XLPE cable insulation with multiple defects [PDF]

open access: yesОмский 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. Part XXIV: The analysis of PD in HVDC equipment

open access: yesIEEE 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".
