Ground Fault Line Selection with Improved Residual Flow Incremental Method
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2013 According to the shortcoming of single-phase ground fault line selection method in the resonant grounded system such as the uncertainty of its device by fast compensation with the automatic compensation equipment, an arc suppression and residual flow incremental method is proposed to effectively choose the earth fault line.
