Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

High Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

Mechanical Properties and Quantitative Analytical Modelling of Micro/Nanocellulose Co‐Modified Insulating Papers With Different Aspect Ratios

High Voltage, EarlyView.
ABSTRACT The incorporation of nanocellulose‐doped insulating paper into the material composition of a given structure has been demonstrated to enhance the material’s mechanical properties and retard the development of cracks. However, the effects of different length‐to‐diameter ratios of nanocellulose are different.

Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

High Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

Signal Extraction and Clustering of Partial Discharge in Motor Insulation Using Temporal Correlation‐Based Clustering

High Voltage, EarlyView.
ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...
