Online Monitoring of Partial Discharges in Large Power Transformers Using Ultra-High Frequency and Acoustic Emission Methods: Case Studies

Energies
Partial discharges (PDs) are one of the leading causes of catastrophic power transformer failures. To prevent such failures, online PD monitoring systems are increasingly being implemented.

Effects of shorter phase-resolved partial discharge duration on PD classification accuracy

International Journal of Power Electronics and Drive Systems (IJPEDS), 2020
<span>Partial discharge (PD) pattern recognition is useful to diagnose insulation condition. PD measurement data is commonly represented in phase-resolved partial discharge (PRPD) format. PRPD is useful as it provides a visible pattern for different PD source and various features can be extracted for PD pattern recognition.

Lipid Nanoparticle Co‐Delivery of mRNA and a Small Molecule Drug for Oral Cancer Chemoimmunotherapy

Advanced Materials, EarlyView.
Co‐encapsulation of p53 mRNA and the small molecule ciclopirox within a lipid nanoparticle yields an all‐in‐one chemoimmunotherapy for oral squamous cell carcinoma. The platform engages caspase‐driven apoptosis in cancer cells while repolarizing tumor‐associated macrophages, achieving tumor reduction in both p53‐susceptible and p53‐resistant models and

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

On the Use of Monopole Antennas for Determining the Effect of the Enclosure of a Power Transformer Tank in Partial Discharges Electromagnetic Propagation

Italian National Conference on Sensors, 2016
A well-defined condition-monitoring for power transformers is key to implementing a correct condition-based maintenance (CBM). In this regard, partial discharges (PD) measurement and its analysis allows to carry out on-line maintenance following the ...

Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation

Advanced Materials, EarlyView.
Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...

Anisotropic Masked Mycobacterium Potentiates Amplified Antitumor Trained Immunity via Spleen Targeting and Myelopoiesis Conversion

Advanced Materials, EarlyView.
An engineered Trojan Mycobacterium, developed via a “peeling‐off and masking‐up” strategy, functions as a powerful splenic myelopoiesis converter. This spleen‐targeted nanomedicine induces trained immunity to reprogram immunosuppressive myeloid reservoirs into antitumoral effectors.

Localization techniques of partial discharges at cable ends in off-line single-sided partial discharge cable measurements

IEEE transactions on dielectrics and electrical insulation, 2016
Partial discharge (PD) field tests are widely used for cable assessment or cable commissioning. Usually, these tests are carried out by means of off-line tests where PD pulses are measured with capacitively coupled PD sensors.

Cation‐π Interaction‐Based Biointerface for Low‐Cost PD‐1 Detection Toward NSCLC Immunotherapy Monitoring

Advanced Materials Interfaces, EarlyView.
A cation‐π interaction‐based biointerface is engineered on a CNT‐FET for label‐free detection of PD‐1. PD‐1 monoclonal antibodies are orientedly immobilized via cation‐π interactions between PCz‐wrapped semiconducting single‐walled carbon nanotubes and the Fc region of the monoclonal antibody.
