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

LEMKE: Partial Discharge Measurements

2017
The LEMKE Partial Discharge Measurements dataset includes ASCII file outputs from PD testing of low density polyethylene (LDPE) and polypropylene film samples using a LEMKE LDS-6 measurement system. Files include PD magnitude, phase, and period number (please note voltage measurements are not valid, the correct applied RMS voltage is in the file name).

Cable model for partial discharge measurements

2016 IEEE International Conference on Dielectrics (ICD), 2016
A transient analysis software for high voltage cables has been developed as an aid to partial discharge measurements carried out to assess the insulation condition of installed cables. Knowledge of the transient behavior of cable systems allow to know if a specific measuring PD system is sensitive enough to detect partial discharge pulses that can ...

Partial discharge measurement and interpretation

IEEE Electrical Insulation Magazine, 1988
An overview is given of partial discharge patterns, their evaluation, and determination of their origin. Some brief comparisons of test equipment considered to be of general interest are made. The intent is to assist practitioners in the interpretation of results as well as in the accurate discrimination between true partial discharges within an ...

Computer — Aided partial discharge measurements

Conference on Electrical Insulation & Dielectric Phenomena — Annual Report 1987, 1987
An instrument is described which makes computer assisted measurements for the identification of the source and nature of partial discharges which may occur in an insulation system. The instrument accepts pulse count, phase, and voltage magnitude information from a commercially available partial discharge detector of the resonant-coupled type.

Experience with UHF partial discharge measurements

Proceedings of 2002 IEEE 14th International Conference on Dielectric Liquids. ICDL 2002 (Cat. No.02CH37319), 2003
Some tests on UHF measuring techniques on transformers and oil-paper insulation models have been reported in literature. The results indicate the feasibility of this method for oil-paper insulation, but are not conclusive. To have a good perspective of this method, UHF partial discharge (PD) measurements were conducted on small oil-paper insulation ...

Partial discharge (PD) measuring techniques

15th IET International School on High Voltage Engineering and Testing 2008, 2008
The physical background of partial discharges will be explained on simple models. The requirements on the complete partial discharge measuring systems including the calibration and evaluation of the measuring results will be discussed and examples of partial discharge measurements on transformers in the laboratory and on site will be presented. Finally

Partial discharge measurements -- frequency related considerations

CEIDP '05. 2005 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2005., 2005
Partial discharge (PD) test circuits have been developed for various test series in different gases in the 13.3 Pa to 101.3 kPa pressure range with a needle-plane electrode arrangement. (The purpose of the test series is to establish results in terms of PD inception voltage, waveforms and rise times.) The paper describes features of the initial and ...

Partial discharge measuring technique

2001
The partial discharge measurement is a typical non-destructive test and it can be used to judge the insulation performance at the beginning of its service time taking into account the reduction of the performance during the service time by the ageing whereby the ageing depends on numerous parameters like electrical stress, thermal stress and mechanical

Basics of Partial Discharge Measurement

2019
Partial discharge (PD) denotes a small, localized electrical discharge in the insulation between conductors, occurring when the local electric field strength exceeds a critical value. Prolonged exposure to partial discharges is known to degrade the dielectric behavior of the insulation and may even lead to complete breakdown. PD testing of high-voltage
