Research of Single-phase Grounding Fault Simulation for Small Current Grounding System

DEStech Transactions on Environment, Energy and Earth Sciences, 2017
Our country generally uses small current grounding system (the neutral point no direct grounding system). Due to the fault current is too small to identify. So the distribution network operators have been plagued by this kind of fault line selection accuracy. This research establishes simulink model to analyze the fault of single-phase grounding system

Single-Phase Fault Line Selection in Distribution Network Based on Signal Injection Method

IEEE Access, 2021
The distribution network with small current grounding mode can ensure high power supply reliability, but it is difficult to locate single-phase grounding fault line. Most of the faults in distribution network are single-phase to ground fault.

Association Between Dinutuximab Beta Exposure and Post‐End‐of‐Treatment Survival in Neuroblastoma: A Weighted Patient‐Level Analysis of Three Clinical Studies

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives The association between exposure to dinutuximab beta (DB) and event‐free survival (EFS) or overall survival (OS) of neuroblastoma patients was assessed using data collected during three clinical trials (five cohorts). Methods A systematic review (March 2026) was conducted to identify relevant studies (prospective; registered DB ...

An adaptive reclosing strategy for UHV AC transmission lines based on phase difference of single-end induced voltage

International Journal of Electrical Power & Energy Systems
In ultra-high voltage (UHV) AC transmission systems, single-phase to ground faults account for more than 80 % of all faults. If reclosing is performed blindly under permanent fault conditions after a single-phase to ground fault, the system may suffer ...
