Evaluation of Non-Uniform Thermal Aging of XLPE Cable Based on Modified Debye Model

open access: yesFrontiers in Materials, 2022
The polarization/depolarization curve (PDC), which contains abundant insulation information, is widely used to evaluate the insulation condition of the cross-linked polyethylene (XLPE) cables. However, the insulation condition assessing the result of the

A Reconfiguration Method for Extracting Maximum Power from Non-Uniform Aging Solar Panels [PDF]

open access: yesEnergies, 2018
Aging affects different photovoltaic (PV) modules in a PV array in a non-uniform way, thereby leading to non-uniform working conditions of the PV modules and resulting in variations in the power outputs of the PV array.

Gene Evaluation Algorithm for Reconfiguration of Medium and Large Size Photovoltaic Arrays Exhibiting Non-Uniform Aging [PDF]

open access: yesEnergies, 2020
Aging is known to exert various non-uniform effects on photovoltaic (PV) modules within a PV array that consequently can result in non-uniform operational parameters affecting the individual PV modules, leading to a variable power output of the overall ...

An Experimental Investigation on Output Power Enhancement With Offline Reconfiguration for Non-Uniform Aging Photovoltaic Array to Maximise Economic Benefit [PDF]

open access: yesIEEE Access, 2021
There are several non-uniform effects on photovoltaic (PV) modules related to aging in a PV array. These subsequently bring about non-uniform operating parameters with individual PV modules, causing a variance in the PV array performance.

Age-related differences in asymmetric synapses across the central inferior colliculus in the Fischer Brown Norway rat [PDF]

open access: yesAging Brain
The rapidly aging populations of industrial countries are commonly affected by age-related hearing loss (ARHL). A broad mechanistic theme to ARHL are imbalances to excitation and inhibition in the central auditory system in response to the reduced ...

Inducing Non-uniform FPGA Aging Using Configuration-based Short Circuits [PDF]

open access: yesACM Transactions on Reconfigurable Technology and Systems, 2022
This work demonstrates a novel method of accelerating FPGA aging by configuring FPGAs to implement thousands of short circuits, resulting in high on-chip currents and temperatures. Patterns of ring oscillators are placed across the chip and are used to characterize the operating frequency of the FPGA fabric.

A Novel PV Array Reconfiguration Algorithm Approach to Optimising Power Generation across Non-uniformly Aged PV Arrays by merely Repositioning

open access: yesJ, 2020
Photovoltaic (PV) module working conditions lack consistency and PV array power outputs fluctuate due to the non-uniform impact that aging has on various PV modules in a PV array.

A modified XY model of transformer oil–paper insulation system including non‐uniform aging and conductance effect

open access: yesIET Generation, Transmission & Distribution, 2021
The accuracy and feasibility of the traditional XY model of transformer oil–paper insulation system are disputable since it ignored the effect of non‐uniform aging and conductance on dielectric response property.

Aging phenomena in non-crosslinked polyolefin blend cable insulation material: Electrical treeing and thermal aging

open access: yesFrontiers in Chemistry, 2022
Non-crosslinked polyolefin blends have become a favorable alternative material to crosslinked polyethylene (XLPE) cable insulation owing to their low power consumption in the production process and good recyclability at the end of service life.
