A Decade of Smart Medium Voltage Switchgear: LPITs and IEC 61850 Advancements

Medium-voltage (MV) switchgear has evolved dramatically over the past decade, driven by the need for greater reliability, efficiency, and sustainability in electrical distribution systems. This paper examines the practical implementation of Smart MV Switchgear in primary distribution networks, focusing on two transformative technologies: Low-Power Instrument Transformers
