Desarrollo de una guía para coordinación de aislamiento en sistemas de distribución, basada en la normativa IEC 60071-2 e IEEE C62.82.1

Abstract

Isolation coordination in electrical distribution systems involves the selection and coordination of various protection measures to ensure safe and reliable operation. Standards such as IEEE C62.82.1-2010 and IEEE Std C62.82.1-2022 provide guidelines for this task, including protection for transformers, switches, and other parts of the system. The IEC 60071-2 standard offers two approaches, statistical and deterministic, for insulation coordination studies, with the latter being suitable for range I distribution systems. A practical case study compares insulation levels and electrical distances for a 22 kV system based on IEEE and IEC standards. Isolation coordination is crucial at all stages of distribution systems, from planning to maintenance, to ensure electrical safety.
