AbstractPartial discharge (PD) can be used to predict insulation failures in power transformers. Accurate detection of particular PD types has a significant role in anticipating forthcoming outages. However, the noise encountered with PD measurements negatively affects the detection accuracy. In this paper, we propose a robust PD detection technique that is immune to noise through efficient frequency domain-based feature extraction from acoustic emission signals. The PD spectrum is first obtained using Fourier transform and then, the low frequency band of 0.05-0.15MHz is used as a representative feature vector. Finally, four different classifiers are used to examine the PD detection accuracy. Experimental results on a benchmark dataset verify the robustness of the proposed method for PD detection, as it achieves 100% classification accuracy for clean PD signals and up to 99.62% for noisy PD signals.
