Statistical Study on Space Charge effects and Stage Characteristics of Needle-Plate Corona Discharge under DC Voltage

Energies, 2019
The air’s partial discharges (PD) under DC voltage are obviously affected by space charges. Discharge pulse parameters have statistical regularity, which can be applied to analyze the space charge effects and discharge characteristics during the ...

Partial discharge current pulse waveform analysis (PD-CPWA) based on PD mechanisms in solid and gas media

Proceedings of 2005 International Symposium on Electrical Insulating Materials, 2005. (ISEIM 2005)., 2005
This paper introduces a novel technique for partial discharge (PD) measurement and analysis: PD-CPWA (PD Current Pulse Waveform Analysis). PD-CPWA focuses on the PD current pulse waveform and its time transition from PD inception to breakdown (BD), which is closely related to PD mechanisms in electrical insulating materials.

Innate Immunocompetent hiPSC‐Derived Neurospheroids Capture Early CNS Responses to rAAV

Advanced Science, EarlyView.
Knowledge of human CNS immune responses to AAV‐based gene therapies remains limited due to the lack of immune‐competent human models. Here, a hiPSC‐derived 3D neuroimmune platform integrating neurospheroids and microglia is established using stirred‐tank bioreactors.

A Building Block to the Design of Partial Discharge Free HV and MV Cables: Modeling Defects and Discharge Inception Voltage

IEEE Access
It is well assessed that partial discharges, PD, are one of the major causes of MV and HV cable system breakdown, thus investigating partial discharge phenomenology and harmfulness is a key topic in relation to electric asset component reliability ...

Theoretical Study of SOF₂ Adsorption on Pd/Pt-Ni(111) Bimetallic Surfaces

Applied Sciences, 2019
Partial discharge has become a serious threat to the stable operation of gas-insulated switchgears. SOF2 is a characteristic decomposition component of SF6 decomposition components under partial discharge, which further deteriorate the severity of ...

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

Advanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

Modelling of partial discharge characteristics in electrical tree channels: Estimating the PD inception and extinction voltages

IEEE Transactions on Dielectrics and Electrical Insulation, 2018
Partial discharge (PD) characteristics are inherently linked to associated electrical tree growth characteristics. This paper employs both phase-resolved patterns and pulse-sequence analysis (PSA) to study PDs in a short branch-tree grown from a metallic needle tip.
