Authors proposed the method estimating ground fault locations independent of ground fault conditions. Verification of proposed method is carried out using simulator to reproduce ground fault phenomenon. As feature of this simulator, resonance frequency obtained from test using the simulator is different from that of the value calculated from inductance and total capacitor of default value in the simulator. To solve the different point is constructed correction formula of inductance. There is validity that the estimation of ground fault locations using the correction formula is carried out using this simulator. The estimation of ground fault locations is carried out when ground fault condition is inductance. The default value of ground fault locations is almost consistent with calculated value obtained resonance frequency using the simulator. In this paper, Authors report that the estimating ground fault locations by simulator for reproducer ground fault is validity from verification result of the proposed method of estimating ground fault locations.
