International EMC standards describe the measurement environment (setup, equipment, frequencies) and applicable limits for the electromagnetic emission testing of lighting equipment, including compact fluorescent lamps (CFLs). These standards consider the compact fluorescent lamp a ‘black box’. In order to better understand the emissions from this type of light source, the operation of the equi...

Ensuring a high level of service reliability is of paramount importance in an all-electric ship. In the literature, shipboard power systems (SPS) have been designed for improved survivability and quality of service (QOS) requirements. This paper presents a two-level topology design approach and develops system-level architectures for SPS that ensure continuity of service and survivability in th...

In this paper, we develop an agent-based model which integrates four important elements, i.e. organisational energy management policies/regulations, energy management technologies, electric appliances and equipment, and human behaviour, to simulate the electricity consumption in office buildings.

This work presents a method based on elementary concepts of electric network for characterization of piezoceramics. A simplified version of Mason’s equivalent circuit is obtained applying basic theorems of electricity. The methodology employed to simplify the circuit is mandatorily presented in the issues addressed in introductory courses of electric circuits. The experimental development can b...

It is estimated that electric drills (ED) have been used in orthopaedic surgeries for bone drilling for more than 50 years in Brazilian hospitals. It is an electric, thermosensitive equipment, not indicated for surgical use, which has not been previously evaluated regarding the sterilization efficacy, being suspect of infection risk. This study evaluated the efficacy of sterilization by ethylen...

Waste of electric and electronic equipment (WEEE) is the fastest-growing waste stream in Europe. The large amount of electric and electronic products introduced every year in the market makes WEEE disposal a relevant problem. On the other hand, the high abundance of key metals included in WEEE has increased the industrial interest in WEEE recycling. However, the high variability of materials us...

The article presents an application of Prony’s method with some known components in the analysis of electric power quality. Modifications of the Prony algorithm broaden the scope of method application. Modification of the filter of known components enables more accurate analysis of the parameters of unknown components and components with known or assumed frequencies. This article presents a com...

In this paper is presented the development of a smart batteries charger for Electric Vehicles (EVs) and Plug-in Hybrid Electric Vehicles (PHEVs), aiming their integration in Smart Grids. The batteries charging process is controlled by an appropriate control algorithm, aiming to preserve the batteries lifespan. The main features of the equipment are the mitigation of the power quality degradatio...

Accurate estimates of heat lost by power equipment facilitate proper sizing of cooling and ventilation equipment required by buildings and industrial plants. Information on heat loss is available in papers published in the 1970s and 1980s, but some of the informationprovided in thesepapers is dated and, in some cases, includes overly conservative assumptions. The main focus of this paper is to ...
