The detection of high impedance faults on electrical distribution systems has been one of the most persistent and difficult problems facing the electric utility industry. Recent advances in digital technology have enabled practical solutions for the detection of a high percentage of these previously undetectable faults. This paper reviews several mechanical and electrical methods of detecting high impedance faults. The significance of these previously undetectable faults is that they represent a serious public safety hazard as well as a risk of arcing ignition of fires. High impedance faults produce current levels in the 0 to 50 ampere range. Typically, HIF exhibits arcing and flashing at the point of contact. Throughout the utility industry, there have been differences of opinion on how often HIFs occur. Normally, utilities do not keep good records on the number of down conductor instances.
