![]() Recently, live- line insulation diagnosis becomes more important and realistic to maintain good insulation conditions of power lines in apartment houses in wide range of residential sizes. Insulation diagnosis is vital issue for safety of urban lives despite of the difficulty of power interruption even for the diagnosis. Okamoto, Tatsuki Taki, Shoji Fukui, Toshiaki Soga, Akiya Ezure, Shoichiro Asano, Jun-Ichi Uto, Yukio Study on Insulation Diagnosis of Power Lines in Apartment Houses Limits are found on the amount of redundancy involved in any such technique. A technique is given which can be used to realize any network by a network which is diagnosable in the above sense. ![]() A characterization of those networks which can be diagnosed using a purely combinational detector is achieved. The fault set considered is the set of faults which only affect one component system is the network. ![]() The diagnosis of systems which are structurally decomposed and are represented as a network of smaller systems is studied. Then notions of realization, fault, fault-tolerance and diagnosability are formalized which have meaningful interpretations in the the context of on- line diagnosis. First an appropriate class of system models is formulated which can serve as a basis for a theoretical study of on- line diagnosis. A complete model for the study of on- line diagnosis is developed. The theory and techniques applicable to the on- line diagnosis of sequential systems, were investigated. On- line diagnosis of sequential systems, 2 ![]() Further investigation into the theory of on- line diagnosis is recommended for three levels: binary state-assigned level, logical circuit level, and the subsystem-network level. Generalized notions of a realization are discussed along with fault tolerance and errors. In this paper, the IPHI project and the recent evolutions are reported together with the construction and operation schedule.« lessĪ model for on- line diagnosis was investigated for discrete-time systems, and resettable sequential systems. In a final step, the IPHI RFQ and the chopper line should become parts of the SPL injector. The output energy of the Radio Frequency Quadrupole (RFQ), was reduced from 5 to 3 MeV, allowing then the adjunction and the test, in pulsed operation of a chopper line developed by CERN for the Superconducting Proton Linac (SPL). This choice should allow to produce a high reliability beam at reduced intensity (typically 30 mA) tending to fulfill the Accelerator Driven System requirements. Recently, a collaboration agreement was signed with CERN and led to some evolutions in the design and in the schedule.more » The IPHI design current was maintained at 100 mA in Continuous Wave mode. The main objective of this project is to master the complex technologies used and the concepts of manufacturing and controlling the HPPAs. Since the front end is considered as the most critical part of such accelerators, the two French national research agencies CEA and CNRS decided to collaborate in 1997 to study and build a High-Intensity Proton Injector ( IPHI). High Power Proton Accelerators (HPPAs) are studied for several projects based on high-flux neutron sources driven by proton or deuteron beams.
