The aphanitic BFR exhibits the lowest 87Sr/86Sr ratio (0.70593). Figure 2 Trace element anomalies of fault rocks normalized by averaged host rock compositions.
One element of superconducting fault current limiter (SFCL) has relative low rated voltage and current compared with power grid voltage and current.
A chemical and isotopic study of veins and different structural elements of the fault zone (protolith, damage zone and fault core), including a mathematical model, was performed to document type, role, and activity of fluid rock interactions during deformation.
Problems of the different elements of the fault clearing system can be of two main types – if the system does not operate when it has to and if it operates when it should not.
In this paper, a new general formalism has been developed to model two important elements of dynamic fault tree, i.e., cold spare gate and sequential enforcing gate, with any arbitrary probability distribution functions.
The first aspect is the research of the basic principle of fault element identification.
The identification of fault element can be realized by the logic information of operation results.
The mechanism of fault element identification is the critical technologies for the FEI-based WARP.
The protection scheme needs two signal transmission to realize the identification of fault element, which can respectively achieve the near backup protection and remote backup protection.
Consequently, the principle and the algorithm of fault element identification based on wide area information are the research hotspot in recent years, which mainly includes two aspects.
