Discriminating Between Capacitor Bank Faults and External Faults for an Unbalanced Current Protection Relay Using DWT

open access: yesIEEE Access, 2020
Capacitor faults are a common issue in modern-day power systems. Such systems employ a traditional mechanism that solely relies on unbalanced relays as an indicator of faults in capacitor banks; however, in the case of a relay trip, operators may find it

Improved Transformer Differential Protection by Adaptive Pickup Setting during Momentary Over-Fluxing Condition

open access: yesAdvances in Electrical and Electronic Engineering, 2020
The differential relaying scheme is universally adopted as the main protection for power transformer. In certain situations, like temporary over-fluxing, this differential protection may malfunction.

Depletion of p75NTR in Schwann Cells Driven by Inflammation Mediates Cutaneous Pain in Psoriasis

open access: yesAdvanced Science, EarlyView.
Psoriasis‐like inflammation induces proliferation and molecular remodeling of cutaneous Schwann cells, marked by reduced p75NTR and increased NGF expression. IL‐17A promotes this process, whereas Schwann cell‐specific p75NTR overexpression alleviates cutaneous pain in vivo.
