Resumen:
Azogues Electric Company is a public utility company that distributes and commercializes electricity. Part of its infrastructure corresponds to a 69 kV sub-transmission line, which for unknown reasons, presented an electromagnetic transient that affected both the potential transformer of the Azogues 1 electrical substation and the power supply. In this context, to analyze and verify which internal or external phenomenon produced this drawback, single-phase short-circuits, switching operations, and direct, indirect, and induced lightning strokes have been simulated and analyzed along the sub-transmission line using the Alternative Transients Program software. Results showed that an induced lightning stroke of approximately 3 kA, which hits the ground at a distance of 50 meters from the sub-transmission line and a distance of 20 km from the substation can produce an oscillogram similar to the one recorded at the Azogues 1 electrical substation facilities.
