Answer Posted / jaimini soni
Sympathetic trips are undesirable relay operations for
unbalanced- or high-load conditions which
occur during or immediately following out-of-section
faults. The root cause of the sympathetic
trip problem is the type and connection of loads served by
distribution feeders. There are two
classifications of sympathetic trips: those which occur due
to delayed voltage recovery
conditions, and those which occur due to the load unbalance
during an out-of-section fault.
