Resumen:
This paper reports a database of power delivery element model parameters required in specialized distribution network software packages. Based on the authors' experience, these parameters are seldom available or recorded by power utilities so that typical values must be used when modeling these elements. Due to space limitations, the parameters listed in this paper correspond to conductors, cables and distribution transformers mainly used in Costa Rica. To compensate this, an additional reference is presented to consider other power delivery elements and materials not included here.
