Investigating the growth of carbon traces in cardboard in oil-paper insulation

Frontiers in Energy Research, 2023
A large amount of contaminants are collected on the cardboard surface of the valve-side bushing outlet of a converter transformer that has been operating for a long period, and can cause the performance of the oil–paper insulation to degrade.

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

Advanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Electrified Damage in Motion Systems

Advanced Engineering Materials, EarlyView.
The electrified damage in motion systems is a fundamental framework presenting the degradation pathway arising from the coupling of electrical energy transport with mechanical contact and interfacial chemistry. The framework positions electrified damage as a distinct degradation regime with unique characteristic surface morphologies and failures of ...

Effect of different contents of nano-SiO2 particles on water diffusion behavior in insulating oil

AIP Advances, 2019
As an important component of the internal insulation system in a transformer, insulating oil will gradually age during the long-term operation of the transformer, which will lead to a degradation of its insulation performance.

Combustion Characteristics and Self‐Extinguishing Mechanism of Novel Self‐Extinguishing Fluorinated Silicone Insulating Oil

High Voltage
Traditional mineral oil has long served as a liquid insulating medium in power transformers. However, its low fire resistance, poor biodegradability and dependence on finite fossil fuel resources, along with its low flash point, contribute to transformer
