1. IntroductionIn the ever - evolving industrial sector of Vietnam, maintaining a reliable and efficient power supply is of utmost importance. One crucial component in achieving this is the auto recloser, specifically the 630A variant. An auto recloser, or automatic circuit recloser, is a precision automatic switchgear device equipped with smart sensors and electronics. It plays a pivotal role in protecting power lines, grid systems, and electrical equipment in industrial settings.2. Functioning

Why do we need a grid with self-healing capabilities?--Recloser controller with 4G/5G communication as the cornerstone at its coreDriven by both energy transformation and digitalisation, the power grid is evolving from a traditional one-way power supply model to an intelligent, self-healing one. The recloser controller based on 4G/5G communication technology has become the core equipment for building a self-healing power grid by virtue of its ‘sensing-transmission-processing-decision-execu
