Residual Flux Density Measurement Method of Single-Phase Transformer Core Based on Time Constant
IEEE Access, 2020 Residual flux density in the single-phase transformer core can dramatically increase inrush current when the transformer is energized. To reduce inrush current, it is necessary to study residual flux density measurement.

Fast demagnetization method for power transformers combined with residual flux measurement
International Journal of Electrical Power and Energy SystemsWhen power transformers are re-energized, the inrush current may be generated and damage electrical equipment. In order to suppress the generation of serious inrush current, the residual flux (RF) in the power transformer core needs to be eliminated ...

Research on Inrush Current Suppression of Transformer Based on Changeable Closing Angle
Zhongguo dianli, 2022 The transformer no-load closing inrush current may cause safety problems in power grid, and the controlled switching technology with fixed target angle still has room for improvement in suppressing inrush current. A transformer inrush current suppression

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