Pemodelan karakteristik arrester pada jaringan transmisi 150kv akibat sambaran petir merupakan salah satu cara yang praktis untuk membentuk jalan yang mudah dilalui oleh arus petir, sehingga tidak timbul tegangan lebih pada peralatan. Pada makalah ini di... see more

In this article is analyzed an urban distribution network of 23 kV typical of the central zone of Mexico. The objective is to determine the maximum spacing of surge arresters on the line that allows reducing the outages of the distribution circuit due to ... see more

Los pararrayos de óxido de zinc (MOSA) son dispositivos utilizados en la protección contra sobretensiones.Actualmente se han desarrollado modelos matemáticos como herramientas de simulación para un mejor análisis delcomportamiento de los MOSA en estudios ... see more

The appropriate circuit modeling of metal oxide gapless surge arresters is critical for insulation coordination studies. Metal oxide arresters present a dynamic behavior for fast front surges; namely, their residual voltage is dependent on the peak value,... see more

Metal-oxide arresters (MOAs) are used to absorb the electrical energy resulting from overvoltages in power systems. However, temperature rises caused by the absorbed energy can lead to the electrothermal failure of MOAs. Therefore, it is necessary to anal... see more

The hot points that occur in the switchyard are caused by currents flowing in the conductor due to obstacles. The frequent heating part is the terminal and connection portion of the switchyard, especially between the two different metals, as well as the c... see more

Pecatu feeder is a feeder that has a radial distribution system configuration, the length of the line is 31 kms . In addition, these feeders have as many as 105 pieces of distribution transformers with a total number of subscribers reached 11,800 subscrib... see more
