System engineering is an interdisciplinary field where engineers, mathematicians, economists, scientists, and other experts can merge their abilities and skills to solve complex systems, dealing with design, analysis, programming, implementation, maintenance, and control. These complex systems can be tangible, such as high-voltage power systems, telecommunication infrastructure, or systems in the aerospace industry, or non-tangible, like computational systems, social environments, or economic problems. The solutions to these problems must ensure safety, reliability, efficiency, and maintainability. System engineering is a fascinating field because it is possible to have different visions for the same problem, providing part of the solution comes from other areas. The main idea is to assemble models (or several submodels) to represent an observed system, making it possible to study the various relationships within the system as well as those between the system and external agents. The division into submodels makes it possible to study each submodel’s performance in the system’s final result. Sometimes, small systems can also be complex due to the number of external agents interfering with the process or the number of observed variables. This book discusses applications of system engineering in different classes of problems and examines how a given solution for a specific problem can be transported and applied to solve another problem. It provides practical and theoretical explanations of problems, explores the application of system engineering tools, and describes the use of intelligent techniques.

Bearing Fault Detection in Induction Machine Using Squared Envelope Analysis of Stator Current

By Valeria Cristina Maria Nascimento Leite, Jonas Guedes Borges da Silva, Germano Lambert Torres, Giscard Francimeire Cintra Veloso, Luiz Eduardo Borges da Silva, Erik Leandro Bonaldi and Levy Ely de Lacerda de Oliveira

In this chapter, motor current signature analysis based on squared envelope spectrum is applied in order to identify and to estimate the severity of outer race bearing faults in induction machine. This methodology is based on conventional vibration analysis techniques, however, it is, non-invasive, low cost, and easier to implement. Bearing fault detection and identification in induction machines is of utmost importance in order to avoid unexpected breakdowns and even a catastrophic event. Thus, bearing fault characteristic components are extracted combining summation of phase currents, prewhitening, spectral kurtosis and squared envelope spectrum analysis. Experimental results with a 0.37 W, 60 Hz, and three-phase induction machine demonstrated the methodology effectiveness.

Current Transducer for IoT Applications

By Erik Leandro Bonaldi, Levy Ely de Lacerda de Oliveira, Germano Lambert-Torres, Luiz Eduardo Borges da Silva and Vitor Almeida Bernardes

The evolution of communication technology and the reduction of its costs have driven several advances in measurement systems. Points that could not be measured before can now be monitored. Points with difficulty to reach or with major security restrictions can begin to have their quantities measured and informed to control centers. This chapter presents one of these evolutions showing a current transducer (CT), which can measure this magnitude, make an initial treatment of the signal, and transmit it to a panel or control center. Besides, this current transducer does not require an energy source to operate, being self-powered by the current it is measuring. Because it is inexpensive, it can be spread through the facilities, supplying the current at various points of the observed electrical network. With signal treatment, useful information can be inserted in this device so that it informs already preprocessed elements to reading devices, becoming part of the world of IoT. This article presents its use in motor condition monitoring at the Pimental hydroelectric power plant.
