The different dielectric strength behaviour that occurs when the metal particles broken off
from the iron core and copper windings penetrate into the transformer oil needs to be …

Insulation degradation may cause inefficient and faulty operation of transformers. The
insulation failures in transformers mostly start with a Partial Discharge (PD) event. For both …

The dielectric performance of pressboards impregnated with mineral oil is one of the key
points in regard to the quality of the transformer's working life. Partial discharges (PDs) …

The potential utilization of pongamia oil (PO) based nanofluid as an insulating material for
electrical purposes is examined in this study through an analysis of its partial discharge …

With increasing transformer voltage levels, the probability of unexplained insulation
discharge failure also increases. These failures often occur despite normal insulation …

Due to its high fire point, degradability, and excellent electrical properties, natural ester (NE)
insulating oils provide an alternative to mineral insulating oils in electrical equipment. At …

This article presents the results of the studies on development of negative streamers in
synthetic ester and mineral oil with electrode system using a pressboard barrier. The tests …

With the development of microelectromechanical technology, the piezoelectric
micromechanical ultrasonic transducer (pMUT) for ultrasonic detection of gas‐insulated …
