New generation of Smart low-voltage switchgear and controlgear assembly

Abstract

In the framework of Smart Grids development, MV switchgear with advanced functionalities such as automation, remote management and monitoring and new distribution transformers with low-voltage regulation and losses reduction have been defined. Nowis the time of the evolution of low‑voltage distribution switchgear and controlgear assembly,moreover with the necessity of Distributed Energy Resources (DER) and Electric Vehicle (EV) charging integration.These assemblies will have an increasingly important role in energy metering with smart low-voltage meters, integrating low-voltage energy monitoring with communications, as well as protection functions, and even evolving increase the operability, with main objectives of improving efficiency and low-voltage network management.
