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".

A Novel Antenna for Partial Discharge Measurements in GIS Based on Magnetic Field Detection
Sensors, 2019 This paper presents a new concept for partial discharge measurements in gas insulated systems (GIS). The proposed technique uses a novel GIS magnetic antenna that measures the magnetic field produced by partial discharges (PD) propagating in GIS.

Application of Huber-similarity measure on PD detection [PDF]
Serbian Journal of Electrical Engineering, 2019 Extraction of Partial Discharges (PD) is a key step in diagnosis and evaluation of the power system equipment condition. In field testing, besides high frequency noise and disturbance, Power Frequency (P.F.) harmonics also couple with PD ...

Feature extraction and ageing state recognition using partial discharges in cables under HVDC
Electric power systems research, 2020 PD detection is an effective way to evaluate the degradation state of cable insulation. The extraction and selection of relevant features from PD raw data have been mostly investigated to recognize the types of insulation defects in HV equipment. In this

Acoustic emission partial discharge detection technique applied to fault diagnosis: Case studies of generator transformers [PDF]
Serbian Journal of Electrical Engineering, 2016 In power transformers, locating the partial discharge (PD) source is as important as identifying it. Acoustic Emission (AE) sensing offers a good solution for both PD detection and PD source location identification.
