Microcomputer Protection Device Series

introduction

The microprocessor-based protection device series is a core protection unit for smart grids, based on a digital signal processor (DSP) to achieve rapid fault identification and precise action. It integrates protection logic for multiple scenarios such as lines, transformers, and motors, supports the IEC 61850 communication protocol, and features fault recording, self-testing, and remote configuration functions. It is widely used in substations and industrial power distribution systems to improve power supply reliability and operation and maintenance efficiency.
