Ricardo Arias of IEEE PES PERU

Many overhead lines with double circuit are located in the highlands of Peru. The failure analysis
caused by lightning in the Andean mountains is difficult to solve. A new electrical model for
engineering failure analysis is proposed using distributed parameters, transitory analysis, combinatorial
model and grounding system equivalent, besides an electrical equivalent for transmission
line arrester for overhead lines and their constraints. The number of lightning discharges captured by the power transmission line and
guard cables have an interesting behavior, in this analysis, a new expression of probability
density function is proposed and a methodology for this installation. Finally the distribution of
the currents and the shielding are required to improve the performance of grounding system and
insulation, this model allows to avoid loss of function, transmission of electrical energy.
