The high voltage power transformer is the critical element of the power system, which
requires continuous monitoring to prevent sudden catastrophic failures and to ensure an …

Power transformer is one of the main equipment in power transmission and distribution
network. Thus, it is important to ensure optimal operation of power transformer for an efficient …

This paper reviews the main features of acoustic emission technique. First, the
characteristics of acoustic signals and their physics are addressed. Then, the structure of …

This article presents a new convolutional neural network (CNN) topology using wavelet
kernels to detect and discriminate single or multiple partial discharge (PD) locations in high …

Broadening the concept of smart grid to include bi-directional interactions between grid and
asset electrical components as regards their health conditions would help optimizing …

Partial discharge (PD) detection is an effective way to find defects and diagnose the
insulation condition of power equipment. During manufacturing and operating, there may …

Power transformers are essential for the distribution and transmission of electricity, but they
are prone to degradation due to faults early on. Partial Discharge (PD) is the most significant …

As a non-destructive local gas breakdown phenomenon within a surface or bulk cavity
surrounded by insulation, partial discharge (PD) contains important information which can …

Partial discharge acoustic detection is an important monitoring tool for power transformer
diagnosis, which was traditionally performed by mounting the piezoelectric transducers on …

This article demonstrates the use of five different methods to estimate partial discharge (PD)
location in an oil insulation system from noisy measurements. The measurements are …
