Isolate only the smallest possible section of the network containing the fault.
The traditional radial distribution system is evolving into a meshed network due to Distributed Energy Resources (DERs), such as solar PV and wind. electrical distribution system protection pdf
: Ensuring safety for personnel and protecting consumer apparatus are critical secondary goals. Protection Philosophy : Effective schemes rely on selectivity (tripping only the necessary breakers), sensitivity (detecting even low-level faults), and Radial vs. Active Systems Isolate only the smallest possible section of the
Based on IEEE and industry standards, the primary devices used in distribution protection include: sensitivity (detecting even low-level faults)
