Partial Discharge Signal Denoising Using the Empirical Mode Decomposition

This paper presents the findings of an investigation into Partial Discharge signal denoising using techniques based on Empirical Mode Decomposition. The denoising techniques are based on thresholding the Intrinsic Mode Functions which result from the Empirical Mode Decomposition of a signal. The results of the tests carried out show clearly that these techniques can produce excellent results wh...

Characteristic Analysis of Partial Discharge Detection in GIS

Abstract Partial discharge (PD) detection is a valuable method for the estimation of GIS condition, and the PD mapping is benefit for GIS defects identification. To investigate the PD characteristic of the GIS model, this paper simulates different PD maps of various fault simulations, and the characteristics of PD map is acquired by the pulse amplitude, phase and the discharge density to identi...

Partial discharge signal detection using ultra high frequency method in high voltage power equipments: a review

Partial discharge (PD) can be detected using ultra high frequency (UHF) method to increase the detection threshold and to improve the performance of on-line measurement of PD in noise environment. The PD emitted energy as electromagnetic emission, acoustic emission and ozone and nitrous oxide gases. We can use this emitted energy to detected PD signal. The best method to detect PD in gas insula...

Partial Discharge Diagnosis on GIS Based on Envelope Detection

In order to detect and identify the defects on GIS, the ultra-high frequency envelope detection circuit and high-speed data acquisition system was designed, and the tests of five typical defects for GIS were made in the laboratory and the envelope signal was acquired based on Ultra-high frequency (UHF) envelop detection circuit. And wavelet denoising technique was used to reduce the white noise...
