Novel Piezoelectric Emergency Opening Sub-System to Improve the Safety and Reliability of Zero-Holding-Energy Permanent Magnet Magnetic Contactors
Conventional switchgear such as relays and magnetic contactors (MC) continuously consume energy to maintain an open and/or closed state, contributing to unnecessary energy consumption, dissipation, and heating.The minimization of such losses has become an important topic in recent years, leading to the development of more energy-efficient technolog
