Partial discharge location in power transformers

IEE Proceedings - Science, Measurement and Technology, 2000
In a power transformer, high levels of partial discharge activity may lead to an insulation failure. If a partial discharge (PD) could be detected and located before the insulation fails, the transformer could be repaired or replaced before any consumers connected to the transformer lose supply. A technique is described in the paper that can be used to

Partial Discharges Waveshape Characterisation

2004
Power transformers have a significantly more complex insulation structure than other types of power devices. The economic penalties incurred by transformer failure, and the resulting outage cost, are considerable.

Propagation of partial discharge signals and the location of partial discharge occurrences

2013 IEEE 8th International Conference on Industrial and Information Systems, 2013
The location of the partial discharge source in transformer insulation was analysed by simulation studies. The partial discharge source was modelled such that it radiates the Ultra High Frequency (UHF) signal. It was observed that there exists a time difference of arrival of the UHF signal at the sensors based on its distance from the location of the ...

Managing remote on-line partial discharge data

2009 IEEE Power & Energy Society General Meeting, 2008
The volume of data produced by existing partial discharge monitoring systems is often too large for engineers to examine in detail, leading to data being ignored and useful indicators of health being missed. The case study reported in this paper recorded 21\thinspace839 events around an HVDC reactor over a six-day period.

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).
