Sensitivity of Voltage Sag Based Fault Location in Distribution Network to Sub-Cycle Faults Conference Paper uri icon


  • © 2014 IEEE. Single-phase-to-ground sub-cycle faults in the distribution network can be located using voltage sag fault location. This paper illustrates how a sensitivity study of measurement imperfections can be used to quantify the impact of sub-cycle faults on voltage sag based fault location. Our results suggest that there is a complex relationship between factors influencing error in fault location because the design of the study covered a wide range of conditions. The more complicated, higher order interactions have a stronger influence on error than any particular input factor alone.
