A Commentary on Partial Discharge Measurement and Detection

IEEE Transactions on Electrical Insulation, 1987
A critical review is presented on the various electrical methods available for partial discharge detection and measurement in terms of their chronological development and application on cable, capacitor, transformer, and machine insulation specimens.

On partial discharge measurement in dielectric liquids

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
Partial discharge detection in dielectric liquids requires particular PD measurement techniques and instruments. Simultaneous partial discharge (PD) measurements that are employed on insulating liquids, using dual narrow/wide band detectors, are ...

The Nature of the Measurement of Partial Discharge

2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019
The measurement of partial discharges in solid insulation is predictive of the long-term performance of the insulation. That makes the measurement very important in high-voltage technology. The topic has been of interest for a long time, and has been extensively studied around the world.

Equipment for the Energy Measurement of Partial Discharges

IEEE Transactions on Electrical Insulation, 1983
The energy dissipated by partial discharges (PD) can be estimated from the U i Q i . It has been described a particular device able to deal with such a calculation using a correlator unit. With gas chromatography analysis a satisfactory correlation was available between the degradation products of liquid (oil) or solid (pressboard) insulation and the ...

Measuring the endurance of films in partial discharges

IEEE Transactions on Electrical Insulation, 1993
A new test assembly for measuring the endurance of polymeric and ceramic films under the action of partial discharges (PDs) is presented. If experiments are performed under controlled ambient conditions (i.e., relative humidity), the test procedure gives times to breakdown which show low scatter. The effects of different test conditions on the times to

On line measurement of partial discharges

2000 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.00CH37132), 2002
On line measurement of partial discharges of equipment while in service has a great deal of potential in saving equipment down time in gas insulated substations (GIS) and gas insulated transmission lines (GITL). To address this aspect of partial discharge measurement there is scope for considerable progress particularly in the area of cables already is

Partial discharge and the measurement in GIS

Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 2002
The focal point of this paper is to study the partial discharge on-line diagnostic measurement system in GIS from the aspect of electrical measurement assuming that there were not any measurement devices before the GIS being put to use. A length of coaxial cable was wound on a magnetic ring.

Partial Discharge Measurement

2014
This chapter is devoted to the measurement of partial discharges (PD) localized in weak spots of dielectrics if subjected to high test voltages. As standards for PD measurement s have been introduced only for quality assurance tests of HV apparatus energized by power frequency AC voltages (50/60 Hz), the following treatment refers mainly to this test ...
