摘要
Abstract
This paper designs an intelligent measurement and control device based on multi-core microprocessor. Live display is used to replace PT as voltage measurement signal, and a new method for ground connection fault diagnosis is presented, which makes intelligent products low-cost and small. The device can automatically cut down and close off fault according to the threshold of failure set by system, at the same time, it can save the fault current waveform and record the message, then pass the message to the up system by RS485 and wireless. It achieves distribution grid firewall function and improves power supply stability and security.关键词
