| Abstract: | When single-phase-to-earth fault occurs on a neutral non-direct grounded power system,it is nexessary for improving the reliability of power supplying to select the faulted line quickly. The paper overviews the principle of single-plase-to-earth fault protection for small current neutral grounding at homt and abroad,and analyzes the advantages and disadvantages of the principles being used currently. Finally,it presents my view on single-lhase-to-earth fault protection. |
