Power transformer is one of the most important high voltage apparatus in any power system
network. The life span of such apparatus commonly relies upon its insulation condition. The …

Snow is a highly complicated atmospheric phenomenon that usually contains snowflake,
snow streak, and veiling effect (similar to the haze or the mist). In this literature, we propose …

The joint time‐frequency analysis method represents a signal in both time and frequency.
Thus, it provides more information compared to other one‐dimensional methods. Several …

In this article, a hypersensitive multispectral partial discharge (PD) optical sensor array was
developed, by which the optical pulses in seven independent bands can be acquired …

In modern power systems, condition based monitoring and diagnosis is essential to ensure
the effective and reliable operation of different high voltage equipment (HVE). Compared to …

Current wavelet thresholding methods for cardiogram signals captured by flexible wearable
sensors face a challenge in achieving both accurate thresholding and real-time signal …

The Savitzky-Golay (SG) filtering is a widely used denoising method employed in different
applications. The SG filter has two design parameters: the window length and the filter order …

This article develops a fully automatic tool for the de-noising of partial discharge (PD)
signals occurring in electrical power networks and recorded in on-site measurements. The …

In electrical engineering, partial discharge (PD) measurement is frequently employed to
detect insulation defects and judge insulation conditions of high-voltage electrical …
