Primary Current Test Method for Transformer Protection Based on Transient Load

open access: yesZhongguo dianli, 2021
When test load is insufficient, the current transformer (TA) secondary circuit test by primary current cannot be completed, which often results in the failure of new transformer protection to be put into normal operation.

Effect of Mth coherent state on the interaction between two two-level atoms and two-mode quantized field

open access: yesJournal of Taibah University for Science, 2022
The objective of this work is to measure the influence of the Mth coherent state on the optics model of two atoms interacting with two-mode quantized field. Also, two atoms interacting together is included in this optics model.

Topological phase transition between non-high symmetry critical phases and curvature function renormalization group

open access: yesNew Journal of Physics, 2023
The interplay between topology and criticality has been a recent interest of study in condensed matter physics. A unique topological transition between certain critical phases has been observed as a consequence of the edge modes living at criticalities ...
