| Abstract: | In this paper,considering the isolated neutral or with resonant grounding in small current grounding system,grounding arc extinguishing capacity of the existing system at low and personal sense of power,the indirect grounding voltage,the device internal ground fault,the non-protection issues,an in-depth method of protection is studied.Based on the use of advanced electronic technologies electrical theory,the above system is altered as an intelligent grounding system for the protection of programs’ running.At the same time,the paper introduces its grounding system,working principle,function and features of the operation of the system. |
