The need for greater reliability and safety of electrical systems has led to increased use of microprocessor based relays, who besides allowing a quick and timely detection of faults in electrical systems presented have ...

In our country the loss of neutral for theft has been increasing more than ten years ago, because of this issue, problems occur in the distribution system. It is in the supply where the loss of the neutral is presented ...

The content of the paper is divided into five chapters, defined as follows: Chapter 1: This chapter presents the important points, called key planning an electrical system such as: taking into account the participation of ...

In this thesis the design and construction of a module for automatic synchronization to the grid of CFE of a synchronous machine 2 KW (220 V, 60 Hz) is presented using as prime mover machine Direct Current (DC) of the same ...

The need for greater reliability and safety of electrical systems has led to increased use of microprocessor based relay that allows rapid and early detection of faults in it. Adaptive protection is seen as the optimal ...

The presence of electromechanical oscillations is a characteristic of any Electric Power System (SEP), as long as the damping associated with this type of oscillations is within the acceptable range or limits for the ...

A lightning strike is the result of the charge equalization of an electric field, which is created from cloud to ground and cloud to cloud. The display of his fall on a map, it is very useful to know the geographical region ...
