Power utilities are struggling to reduce power failure incidents in substations and their
components to operate more reliably and economically [1]. Many power failures are …

Condition monitoring of an operating apparatus is essential for lifespan assessment and
maintenance planning in a power system. Electrical insulation is a critical aspect to be …

Partial discharge (PD) measurements provide valuable information for assessing the
condition of high voltage (HV) insulation systems, contributing to their quality assurance …

One of the most common failures or breakdowns that can occur in high-voltage (HV)
equipment is due to partial discharges (PDs). This occurs as a result of inadequate …

The article presents in detail the construction of a low-cost, portable online PD monitoring
system based on the acoustic emission (AE) technique. A highly sensitive piezoelectric …

Partial discharges (PD) are the most common and harmful threat to the health of electrical
insulation of high voltage (HV) and high field (HF) equipment. The occurrence of PD activity …

Partial discharge (PD) is not only an important symptom for monitoring the imperfections in
the insulation system of a gas-insulated switchgear (GIS), but also the factor that accelerates …

The analysis of partial discharge (PD) signals has been identified as a standard diagnostic
tool for monitoring the condition of different electrical apparatuses. This study proposes an …

We propose a high sensitivity optical fiber sensor for detecting the acoustic emission
generated by the partial discharge in gas-insulated-switchgear (GIS). A model is established …

Monitoring the partial discharge (PD) activity of power equipment insulation is crucial to
ensure uninterrupted power system operation. PD occurrence is highly correlated to …
