Abstract

This project's main objective is to develop an electrical project to electrify a condominium for a tourist resort in the Municipality of Praia do Bilene, a project belonging to the company Rising Construções, LDA. In the technical aspect of the project, the criteria for determining the power to be contracted are presented. In order to achieve the objectives set, it was necessary to dimension the interior and exterior lighting circuits, sockets for general and specific use, sizing of the PT Cabinet and not forgetting the sizing of public lighting in the parking lot. In this context, a 75kVA capacity distribution transformer is required for its power supply. However, a cabinet will be installed next to the PT in order to protect and supply the other circuits. The cabinet comprises a compact 100A circuit breaker, four 5kA busbars, nine 40A capacity NH fuses, a 25A NH fuse and a 25A circuit breaker. For the preparation of this report, the Rules and Regulations in force in the national territory and abroad were observed, the rules and regulations are described throughout the report. Below are some articles consulted: Article 435 of the R.S.I.U.E.E , 25 VA/m2 for lighting circuits and sockets for general use, 10 VA/m2 for garages/parking, 80 VA/m2 for Air Conditioning Systems, Washing or drying machines 3.3kVA, 2kVA water heating. According to Art. 420. ° RSUIEE, The installations of use, fed from public distribution networks, whose total power exceeds 6.6 kVA, will be three-phase, unless previously agreed by the distributor. The powers must be distributed among the phases, as much as possible in a balanced way. In all that is omitted in the integral parts of this PROJECT, the Regulations and Norms referred to and other regulatory provisions in force, and also the decision of the inspection and/or owner of the work, as well as of the designer (TRADUÇÃO NOSSA)
