Resumen

This paper presents a method to evaluate the ampacity of medium-voltage underground cables, which takes into account the construction of a terrain thermal resistivity map, the route of the medium voltage feeders, the modeling of the cable, the modeling of the installation characteristics, and the information of the amperage passing through the feeder obtained from the SCADA system. This method includes the processing of the information in its own software created in Visual Studio and programmed in Visual Basic, which takes as a calculation basis both the IEC 60287 standard for stationary load regime and the IEC 60853 standard for cyclic load regime. This method is applied for an electric distribution company in Peru, evaluating the ampacity for a section of a feeder.
