“…According other works [13] [14], arcing during the HIF exhibits high frequency current harmonics is demonstrated and these harmonics components are detected at substation for relative long distances. Beyond current analysis from measurement, voltage waveforms associated with the HIF arcs are studied [15]- [16] to implement new pattern recognition methods and even a superposition of voltage signals method to detect low current faults [17].…”

One of the electrical distribution company's aim is to maintain the power supply to customers. In rural distribution feeders the proliferation of nest over the electric towers has committed this objective and actually the efforts of electrical companies to maintain clean their lines are huge. The problems occur when parts of nest caused the electrical contact between conductor and steel tower producing High Impedance Faults (HIF) and sometimes tripping protection. In this paper this problem is addresses, experimental tests were carried out in MV feeder to show this type of HIF is detectable from substation and a characterization of signal measured could be used to relay protection reprogramming.

Abstract. Detection of High Impedance Fault (HIF) that is mainly occurred in MV power systems has been a challenge due to its low current magnitude. A new HIF detection approach based on correlation functions is applied on the voltage and current signals in this paper. Twelve indices based on correlation functions are implemented and tried on a lot of cases. Some of them which have clearly different values for no-fault and HIF conditions are chosen. Simulation results prove the efficiency of proposed method for HIF detection.
