Intermittent Earth Fault Passage Indication in Compensated Distribution Networks

An intermittent or restriking earth fault is a special type of that common mostly in compensated cable networks. A great deal effort has gone into protection against this fault. However, locating not received much attention. Therefore, there need to have reliable method for repair the damaged cable. In paper, principles new developed transient faults on distribution networks are presented. The proposed employs negative and zero sequence currents, no voltage measurement required, which means potential reduce cost when implemented practice. It intended mainly typical where resistance range few ohms. Real data obtained from practical field tests used explain phenomenon. series disturbance recordings validate method.
