Arcing and/or downed distribution conductors, although not of concern from an equipment damage point of view, do pose a safety threat from a personnel and property perspective. Traditional protection devices typically do not detect the fault current levels resulting from these conductor conditions. The ability to detect High Impedance (HiZ) faults has been a topic of research and development for over...
The traditional solutions for protecting networked distribution lines, sub-transmission lines, and industrial facility incoming supply lines use some form of pilot protection. A significant challenge for pilot protection, especially in retrofit situations, is the cost of installing pilot communications channels. Digital radio is an inexpensive method to provide digital communications for pilot protection...
Networked distribution lines, sub-transmission lines, and industrial facility incoming supply lines have always presented an interesting protection challenge. As the number of distributed generators and cogeneration facilities increase, directional overcurrent protection and distance protection may not be selective enough for reliable protection without the implementation of pilot protection schemes...
