Estudo de Caso Acesso aberto Avaliação de conformidade das instalações elétricas de baixa tensão: sua importância, seu processo de realização e suas vantagens(2018) Silva, FabianoThe topic safety is one of the most relevant factors when the theme is electricity. Any carelessness in the handling and operation of electrical power can have fatal consequences. Based on this, every scope of projects involving the electrical means has its eyes constantly turned to safety. Since the project development, passing through the various installation stages of the electrical components, till the indispensable stage to ensure this safety, which is the inspection. This way, all these processes that compete for the electrical installation are supported by the Brazilian standards pertinent to each segment, serving as a technical basis for the execution of the inspection. This is the tool to guarantee the compliance with the standards, aiming at safety and various secondary benefits. In Brazil, although we have already demonstrated some bills, the electrical inspection on the instalations is still voluntary. Directly connected to this, we can observe a gradual increase in the number of accidents of electrical origin, a fact that could be reversed, if by chance the inspection occurred to be compulsory, as in the example of others countries where there is already mandatory inspection for any movement of the property, aiming at the safety of users.Estudo de Caso Acesso aberto Comparativo entre usinas fotovoltaicas: usinas com sistema tracker ou com estruturas fixas(2017) Martins, Thiago MüllerThe present case study aims to demonstrate the most efficient between two types of photovoltaic plants, the one with fixation structures with tracking of solar radiation or the plant with a system of conventional metal fixation structures. Here will be presented a technical and economical comparison between the two models of photovoltaic power plant, using the appropriate tools for it. For comparative purposes, the same equipment will be used in both systems, except for the fixing structures. The same geographical location will also be used in both systems to avoid distortions of radiation from one power plant to another. As for the economic base, the option chosen to study the return on investment was the Simple Payback, which will be based on the initial investment to implement the project and the value of the sale of the energy generated by it in the free energy market.Estudo de Caso Acesso fechado Transferência de ativos de iluminação pública(2017) Spessatto, Javan LeonardoPublic lighting begins for the initiative of the population in order to essentially prevent the commission of crimes. Over time, it is observed several attempts by the State to improve the energy efficiency of public lighting (IP), but many of these failed. In Brazil, the electricity sector has undergone drastic changes with the publication of Laws No. 10,847 and No. 10,848 / 2004, which transfers the electricity sector of the state monopoly to a market model. This change, culminating in the publication of Normative Resolution 414/2010, which defines IP as a public service and provides for the transfer of responsibility to design, implement, expand, operate and maintenance of public lighting, the distribution to municipalities, directly or by concession or permission. Today, after the deadline for completion of the transfer of public lighting assets to municipalities, about 8% of Brazilian municipalities have yet to assume the AIP. This study will evaluate whether this change of responsibility, resulted in improved street lighting and cost savings.
