Failure Probability Evaluation of GIL Tri‐Post Insulators Under Electromechanical Stresses

High Voltage, EarlyView.
ABSTRACT Based on the energy theory, this paper proposes an evaluation method for the breakdown failure probability of the tri‐post insulator in a gas‐insulated metal‐enclosed transmission line (GIL). Various internal defects, vector forces and torque forces were considered, along with the application of an AC voltage.

Investigation of Dielectric and Thermal Properties of Mineral Oil‐Based Fe3O4‐Coated SiO2 Core‐Shell Nanofluids

High Voltage, EarlyView.
ABSTRACT This study investigates the dielectric and thermal properties of transformer oil‐based nanofluids incorporating Fe3O4‐coated SiO2 core–shell nanoparticles as nanofillers. The nanoparticles were synthesised with varying shell thicknesses, and two samples underwent surface treatment.

Unravelling the Correlation Between Moisture and TDDB in Galvanic Isolators Based on Polymeric Dielectrics

High Voltage, EarlyView.
ABSTRACT In this paper, the impact of moisture on the time‐dependent dielectric breakdown (TDDB) in polymeric dielectrics for galvanic isolators is investigated experimentally. Through ad hoc test schemes, device lifetime under electrical stress is quantitatively correlated to the moisture concentration in the samples by monitoring the latter via the ...

The Breakdown and Self‐Clearing Performance During the Energy Harvesting Process of Dielectric Elastomer Generators Using Single‐Walled Carbon Nanotubes Electrodes

High Voltage, EarlyView.
ABSTRACT For dielectric elastomer generators (DEG), electrical breakdown is the main failure mode during their working cycle. The application of self‐clearing electrodes is of great significance to avoid a single breakdown leading to the failure of the entire generator.

Polyamide Acid–Based Surface Modification of Poly(p‐Phenylene Benzobisoxazole) Fibres Reinforcing Syntactic Foam for Using Them as High‐Performance Insulating Core Material

High Voltage, EarlyView.
ABSTRACT The insulating core is an important part of pillar composite insulators used in power transmission systems. Traditional insulating core materials suffer from various problems that can threaten the reliability of insulated equipment. Syntactic foam (SF) exhibits excellent properties, such as a low density, water penetration resistance and high ...

Dynamic Bayesian Network for Continuous Health Index Estimation and Condition Assessment of Power Transformers

High Voltage, EarlyView.
ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

High Voltage, EarlyView.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.
