An electrical distribution architecture has a vital impact on the performance of an installed system throughout its lifecycle. The architecture of an installation involves the configuration, the choice of power sources (utility and alternate power source), the definition of the different distribution levels, and the choice of equipment. Previous papers have(More)
In electrical power systems, the fault frequently involves arcing and burning of wiring exposed to mechanical damage and other insulation stresses including wiring not fixed and connected by flexible cords and cables. IEC Standard 60364 ends the design of electric power systems at the outlets of branch circuits or at the fixed equipment. A complete design(More)
The International Electrotechnical Commission (IEC) publication 60364-4-41 “Electrical installations of buildings” fifth edition offers a layout rationalized of complete protective measures against electric shock. To provide an overall analysis of the protection by automatic disconnection of supply, the author suggests a unified model for all(More)
The measure of the ground resistance in a large grounding network needs placement of current electrodes at a great distance. In urban areas, where buildings' growth is adjacent to a power system, choosing suitable locations for auxiliary electrodes becomes increasingly difficult since rigorous ground resistance measures can impossibly be made. This paper(More)
In the last years important improvements are developing in the European Union EU electrical systems: the process of electrical market liberalization, extended to all the customers, small and residential included, and a strong encouragement towards the energy saving and the installation of small renewable power sources. The actual distribution system for low(More)
Modeling of the electric system “architecture” aims to achieve performances of safety, maintenance, operation, and reliability. This paper discusses the criteria in designing special cases, such as roadway tunnels, that need a structured architecture complying with electrical loads extensively distributed and with installation requirements(More)
In the operation of electrical installations, risk assessment evaluates hazards and conflicts. A kinematics analogy for analyzing the risk of “collisions” offers a new approach for operational procedures and allows the introduction of a “transition” theory for intersections. The architecture of electrical installations can be(More)
The architecture of a power system can be configured in increasing complexity related to its exigencies, taking actions on the sources and on the configuration. In the failure cases, it has to guarantee availability and integrity, the time to repair the components has to be compatible to avoid the loss service continuity. The paper relates on the special(More)
For the near to generator short-circuit analysis, it is well known that a rigorous calculation procedure requires the use of complex dynamic models of power system components. In most practical cases, however, it is sufficient to adopt simplified and standard based calculation methods. For these cases the paper suggests a new approach of the short-circuit(More)
The aim of this paper is to present shortly syntax and semantics of a language to program operational procedures. This formal language is a unified suite of symbols, meanings, and codes used on the basis of conventional rules. Symbols have to be related to meanings and to be shared: operational, mathematical, and graphical symbols shown are preferred but(More)
