Abstract :
The paper presents a simple relaying detection scheme for high impedance faults (HIF) in radial utilization and distribution feeders. The scheme is based on the concept of quasistatic ripple harmonics, sub and super harmonic frequencies usually associated with low level currents during arcing faults due to high impedance type (HIF) faults
