Abstract
For the 10 kV boundary switch controller reliability fault isolation boundary switch controller designed in this paper on the hardware of CPU dsPIC33EP512MU810 with high performance and special electric power quality measurement chip MCP3903, software gives a practical TDFT non synchronous sampling measurement method. The boundary switch controller judges the ground fault according to the first 1/4 cycle, zero sequence voltage and zero sequence current direction of the small current grounding.The master station is communicated with each boundary switch controller through the 4G network, and the boundary switch controller is managed and maintained so as to facilitate data management. The experimental results show that the design is accurate and reliable in separating user fault.
