The company is located in one of the major petroleum production areas in Colombia, and because of a massive growth in this sector, the electrical company expanded its networks in a radial way.

ComiXology Thousands of Digital Comics. Table 9 shows the results graingrr the short circuit current in kV substations, proving they do not exceed the protection capacity; therefore, they do not represent a risk to the protection equipment. Conclusions This study highlights the importance dd small and medium companies in the electrical sector that nowadays are growing, updating, modeling and performing simulation of their electrical systems.


Amazon Music Stream millions of songs. P Electric Power System is completely radial; therefore, it is weak, with low reliability and robustness.

Includes full answers and cross references to the relevant pages in the parent text. Between andthe system had faults and meltdowns Table 5. Learn more about Amazon Dd.

Also, technical information about the bus configurations, power transformers, conductors, phase distance, insulation levels, among others, for modeling and system simulation, were taken. I’d like to read this book on Kindle Don’t have a Kindle? The company offers electrical services to 98 regulated and unregulated users [ 1 ]which generates a great responsibility for improvement and constant updating of the power systems.

P Casanare, the distribution system is To compare, measure, and test the acquired data, appropriate formats to record each visit to the electrical substations were created.

Figure 3 shows the single-line diagram of Enerca S. The inductance and capacitance parameters of the lines were determined using the Geometric Mean Graingsr GMR method and the conductor’s manufactures manuals. Proposals to improve the electrical system The analysis of the simulations results permitted the identification of six immediate proposals to correct the Would you like to tell us about a lower price?


The second simulation was made with the forecast demand for the year according to the growth projection for the three geographical areas covered by the electrical system; stecenson used a linear regression according to the growth in current years.
