Defining Lines of Defense Against Change Propagation Using Cause‐Consequence Analysis

open access: yesSystems Engineering, EarlyView.
ABSTRACT Complex engineered systems are the core of modern society. So that engineered systems and infrastructure can be sustainable and offer value over the course of their lifespan, there is a growing need for such systems to be changeable. Yet, establishing and operationalizing changeability can be challenging due to the potential for change ...

Dynamic Modal‐Based Vibration Characteristics Analysis and Looseness Fault Diagnosis in Transformer Winding

open access: yesHigh Voltage, EarlyView.
ABSTRACT Limited by the theoretical basis and diagnostic methods, the winding mechanical condition monitoring often requires both normal condition vibration signals and present vibration signals, and the winding mechanical condition identification is completed by comparing with the normal condition signals.
