Optimal Frequency Value to Detect Low Current Faults Superposing Voltage Tones

Single phase to ground low current faults (LCF) are difficult to be detected with common fault detection techniques. Therefore, several specific methodologies have been developed to identify LCF in an easier way. Among these methodologies, a method based on superposing voltage tones has been propose...

Zusammenfassung:Single phase to ground low current faults (LCF) are difficult to be detected with common fault detection techniques. Therefore, several specific methodologies have been developed to identify LCF in an easier way. Among these methodologies, a method based on superposing voltage tones has been proposed. This method requires defining the frequency of the tones that have to be superimposed.
