A challenging problem in the protection of power transformers is the fault detection and
diagnosis (FDD). FDD has an essential role in the reliability and safety of modern power …

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 …

The detection of partial discharge (PD) activities in high-voltage equipment can be
conducted according to several mechanisms of signal detection, including electromagnetic …

Epoxy resin is one of the most common polymers used as part of the insulation system in key
electrical assets such as power transformers and hydrogenerators. Thus, it is necessary to …

During the last two decades, partial discharges (PDs) modelling methods have been used
as a complement of insulation diagnosis systems of electrical assets. Finite‐element …

Power transformers are key electrical assets in power networks. Their lifetimes are estimated
to be around 40 years if they are properly maintained. However, thermal, electrical and …

This paper deals with a time-frequency analysis of the measured partial discharge (PD)
currents in different insulation gases. These gas environments consist of a pure SF6 …

Acoustic analysis is a substantial method for identification of the defects in high tension
cables. High tension underground cable defects are worth detection using acoustic sensors …

The classic definition goes something like this:“partial discharge is an electrical discharge
that shunts only part of the insulation between electrodes at different potentials”. We have …
