Improving interruption performance of mechanical circuit breakers by controlling pre-current-zero wave shape

open access: yesHigh Voltage, 2019
Mechanical circuit breakers (MCBs) are the limiting component for current injection HVDC circuit breakers. Improving their interruption performance reduces requirements for capacitance and inductance needed in the injection circuit and thus space use and

Optimization of reactive power in distribution networks with DG based on improved particle swarm algorithm [PDF]

open access: yesE3S Web of Conferences
The integration of Distributed Generation (DG) into the distribution network can effectively alleviate the problems of energy shortage and air pollution, but the DG output has the characteristics of uncertainty and randomness, and the integration will ...

Ageing behaviour of a polyethylene blend: influence of chemical defects and morphology on charge transport

open access: yesHigh Voltage, 2020
The properties of novel cable insulation systems will rely critically upon the morphology of the material. Here, a blend of high and low-density polyethylene (PE) was processed in order to generate three sets of samples with different morphologies.

Charging models for airborne suspended particles around HVDC lines

open access: yesHigh Voltage, 2021
Ground total electric field (GTEF) is a vital parameter in the field of electromagnetic environment of high voltage direct current (HVDC) lines. Some experimental works reported that airborne suspended particles can be charged in the corona ion flow of ...

The Role of Voltage-Gated Sodium Channels in Pain Signaling.

open access: yesPhysiological Reviews, 2019
Acute pain signaling has a key protective role and is highly evolutionarily conserved. Chronic pain, however, is maladaptive, occurring as a consequence of injury and disease, and is associated with sensitization of the somatosensory nervous system ...

Electrical Treeing of SiR and SiR/Fe3O4 Nanocomposites in High Magnetic Field

open access: yesIEEE Access, 2023
This paper investigates the effects of high magnetic field on electrical treeing of silicone rubber (SiR). Experimental results show that electrical trees are more easily to be initiated and spread further along the direction of electric field under the ...
