Transformers play an essential role in power networks, ensuring that generated power gets
to consumers at the safest voltage level. However, they are prone to insulation failure from …

Partial discharge (PD) as one of well-known signatures of defects in the insulation system of
high voltage equipment has been studied over eight decades. It is of a great interest to …

In this paper, the rapid aging due to Partial Discharge (PD) activity was investigated in
unaged and thermally aged oil-impregnated paper with a disk-shaped cavity between the …

Experimental and theoretical results concerning partial discharges in liquids are presented.
Experiments on the initiation of partial discharges in floating up bubbles under low …

Partial discharges (PD) in floating bubbles and in microspheres made from thin glass walls
in transformer oil were studied experimentally and theoretically. In a test cell, the PD …

The focus of this research is on the insulation structure where radial and axial spacers
connect in a power transformer. The interaction between the occurrence of partial discharge …

Here it is considered partial discharges in the bubbles inserted in the fluid volume in the
case of electrode systems" plane-plane" and" point-plane". The calculated" true" and" …

Identification of different partial discharge (PD) sources may be improved by the use of non-
sinusoidal waveforms of the testing voltages. For instance, surface discharge (SD) and …

Manufacturing process of oil immersed Power Transformer (PT) has significant effect to the
value of its partial discharge (PD). PD is one of the most important parameters of PT to …

The partial discharges in transformer oil are simulated. Here are considered partial
discharges in bubbles, inserted in bulk of liquid in cases of electrode systems “plane-plane” …
