Three-Phase Transformer Inrush Current Reduction Strategy Based on Prefluxing and Controlled Switching

open access: yesIEEE Access, 2021
Inrush current with high amplitude is generated when the transformer is energized. On the one hand, it will have a negative impact on the safety of the transformer itself, and even cause the relay protection to malfunction.

Analysis of the Electromechanical Characteristics of Power Transformer under Different Residual Fluxes

open access: yesEnergies, 2021
When the electromagnetic transients occur in a power transformer, an inrush current is generated in its winding. The inrush current not only affects the performance of the transformer windings, but also affects the lifetime of the transformer.

Study on the residual flux density measurement method for power transformer cores based on magnetising inductance

open access: yesIET Electric Power Applications, 2022
When a power transformer is reconnected to a power grid, if the residual flux in its iron core is large, significant inrush current may be generated and result in closing failure.

Comparison of the impact of high-flux dialysis on mortality in hemodialysis patients with and without residual renal function. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: The effect of flux membranes on mortality in hemodialysis (HD) patients is controversial. Residual renal function (RRF) has shown to not only be as a predictor of mortality but also a contributor to β2-microglobulin clearance in HD patients ...
