High Impedance Fault Detection On Distribution Feeders
نویسندگان
چکیده
The ability to detect High Impedance (HiZ) faults has been a topic of research and development for over 30 years. About seven years ago, products began to appear on the market that could securely perform this function. Over this time period, several hundred HiZ detection devices have been placed in service and have performed to expectations. This paper reviews the operating principle of HiZ fault detection, looks at the application issues encountered over this time, highlights some of the actual detections, and looks at possible future directions of the technology.

Detection of high impedance faults in distribution networks using Discrete Fourier Transform
In this paper, a new method for extracting dynamic properties for High Impedance Fault (HIF) detection using discrete Fourier transform (DFT) is proposed. Unlike conventional methods that use features extracted from data windows after fault to detect high impedance fault, in the proposed method, using the disturbance detection algorithm in the network, the normalized changes of the selected fea...

The low fault current of high-impedance faults (HIFs) is one of the main challenges for the protection of distribution networks. The inability of conventional overcurrent relays in detecting these faults results in electric arc continuity that it causes the fire hazard and electric shock and poses a serious threat to human life and network equipment. This paper presents an HIF detection algori...

متن کاملDetection of High Impedance Faults Using Artificial Neural Networks
High impedance faults (HIF) on electric power distribution feeders are of a great concern to electric power utilities. These faults often occur when a bare conductor breaks and falls to ground through a high impedance current path [1]. Some HIFs draw sufficient current to be cleared by overcurrent protection, however, many HIFs draw only small amount of current, which makes them difficult to de...
