Effect of Remote Back-Up Protection System Failure on the Optimum Routine Test Time Interval of Power System Protection
Appropriate operation of protection system is one of the effective factors to have a desirable reliability in power systems, which vitally needs routine test of protection system. Precise determination of optimum routine test time interval (ORTTI) plays a vital role in predicting the maintenance costs of protection system. In the most previous studies, ORTTI has been determined while remote bac...
متن کاملProtection of Mesopore-Adsorbed Organic Matter from Enzymatic Degradation
Synthetic mesoporous alumina and silica minerals with uniform pore geometries, and their nonporous analogues, were used to test the role of mineral mesopores (2-50 nm diameter) in protecting organic matter from enzymatic degradation in soils and sediments. Dihydroxyphenylalanine (L-DOPA), a model humic compound, was irreversibly sorbed to both mineral types. The surface area-normalized adsorpti...

متن کاملOperating System Protection Domains
One of an operating system's duties is to provide a trustful security architecture to protect user information from threats coming from all aspects the information world. Trojan horses, viruses, and other threats are all aimed at users' personal information. Therefore, the concept of access control has been introduced to system security area years ago. Typically, it guaranties that only process...
متن کاملSmart Machine Protection System*
A Machine Protection System implemented on the SLC automatically controls the beam repetition rates in the accelerator so that radiation or temperature faults slowthe repetition rate to bring the fault within tolerance without shutting down the machine. This process allows the accelerator to aid in the fault diagnostic process, and the protection system automatically restores the beams back to ...
