Engineering Webinar Series: High-Impedance Fault Detection

August 13, 2024

Who Should Attend:

Engineering personnel and others who would benefit from an understanding of current electric utility engineering principles and practices.

Webinar Overview:

When energized conductors contact poorly conductive surfaces, they create high-impedance faults (HIFs) that are difficult to detect and problematic to clear by traditional equipment which creates a safety concern for the public.  This webinar explains the characteristics of a high impedance fault and the system conditions that can lead up to the
occurrence of these faults. The presentation will discuss some of the historic HIF detection methods used as well as some new and emerging technologies under use and development.
