Avaliação das impedâncias em pontos de acupuntura

An experimental study in dogs was accomplished to evaluate impedances at the acupuncture points and the relative false points. According to the physics concepts and the Ohm’ Law, an electrical circuit was set up to determine the impedance. This circuit was introduced into three experiments in anesthetized dogs with needles at selected points. In the first two experiments, was applied an alternating tension with 200Hz frequency in the circuit and, in the last experiment, the frequency was increased to 10kHz, the tensions and electrical currents were measured between every pair of points for the all experiments. The impedances were calculated with the values obtained by experiments. The analysis of impedance values indicated that there is a coherent relation between the results and the applied frequencies in circuit, so just at high frequency condition admits the correct measurement of total impedance, therefore the last experiment gave the result which agreed with the theory, that the impedances at acupuncture points are lower than the impedances at false points

Aplicação do conceito de geração distribuída a um sistema fotovoltaico residencial

This work presents a study about distributed generation using photovoltaic systems in the context of smart grids. The characteristics of a Smart Grid and the several aspects this concept involves - distributed generation among them - are discussed. There are also examples of equipment, like smart meters, and of national and international projects. The specificities of distributed generation and the rules and standards necessary in this sort of installation are talked through with focus in the solar energy generation method. Regarding photovoltaic systems, the working principles of the panels are presented, along with its main electrical characteristics and the technologies available. Finally there is a study concerning the sizing of a distributed generation system that involves photovoltaic panels in a residential plant. An analysis of the costs and return of investment period is made about the specific case in consideration.

A influência da temperatura nas impedâncias de sequência de condutores utilizados na rede primária de distribuição

Distribution networks are formed by long lines that carry electricity substations to homes and industries. These lines have associated impedance and depending on operating conditions of the network these impedances may vary. This paper provides a detailed analysis of the effects observed in studies of voltage drop, short circuit and electrical losses, when considered the drivers sequence impedances used in primary distribution network at different temperatures. Therefore, it is initially presented a calculation methodology and details the factors that influence the final values. The methodology presented tackles in a practical way the main factors that directly or indirectly influence the values of the impedances as an emblematic example and will be properly dealt with throughout the paper is the effect of temperature on the values of the sequence impedances. More specifically is dealt with the case of XLPE cables protected, by having a higher maximum operating temperature than the operating temperature of the network. The effects observed in the power flow generated when considering the impedance values at both temperatures were analyzed. The impedance drivers tend to increase with increasing temperature. Thus the impedance of the conductor XLPE protected will tend to be greater for the maximum operating temperature for which the operating temperature of the network, resulting in greater voltage drop and higher electrical losses
