| Abstract: | Using portable DC earth fault detector to locate DC earthing may lead to two-point earthing and equipment tripping, thus impacting the stability of power grid. With the mistrip of equipment due to the use of the detector in some 110 kV substation for example, the influence of portable DC earth fault detector on operation of power equipment is analyzed in this paper. |
