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).

The Effect of Humidity on Partial Discharge Measurement

2006 IEEE 8th International Conference on Properties and applications of Dielectric Materials, 2006
This paper is a study of the effect of humidity on partial discharge measurement in rotating machine. As we know, partial discharge measurement is effected by several factors and the humidity is one of the most important factors. To study the effect of humidity on partial discharge test, slot defect stator bar models were manufactured for data ...

Intelligent partial discharge measurement device

Proceedings of 1994 IEEE International Symposium on Electrical Insulation, 2002
This paper introduces a entirely new intelligent partial discharge measurement device that integrates with a microcomputer, A/D, time series control and the filter amplifier circuit for analog signal. It has four independent parallel A/D channels, the highest sampling frequency is 20 MHz and data store is 512 K.

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

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 ...

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 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

On the UHF partial discharge measurement in transformers

2003 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2004
Partial discharge detection sensitivity of three types of UHF partial discharge (PD) couplers, reportedly used in the literature, has been studied in comparison using experimentally simulated discharges and those discharges observed during PD acceptance testing of transformers.

Interpretation of digital partial discharge measurements

IEE Colloquium on PD Display Systems and Analytical Software, 1996
The presence of partial discharges is one of the most prominent indicators of defects and ongoing degradation processes in electrical insulation systems. On-line partial discharge measurements provide information about progressing degradation under operational stress or defects which are only excited by the operational stress (e.g.

Partial discharge measurements: possibilities and limitations

[1992] Proceedings of the 4th International Conference on Conduction and Breakdown in Solid Dielectrics, 2003
Several aspects of partial discharge (PD) measurement and processing of PD data are discussed. It is pointed out that the ABC equivalent is not a fully valid equivalent of a void in the insulation and should be used with some care. The use of broadband measuring systems gives a gain in sensitivity, but calibration can be a problem when they are used on
