Current Duration, C57.109-1993. Use through-fault
event data to schedule proactive transformer bank main-
tenance and help justify through-fault mitigation efforts.

to indicate excess through-fault current over time.
Load Tap Position and Control
Monitoring
The SEL-2414 supports load tap position and control
(LTPC) monitoring by using digital inputs in the
binary-coded decimal (BCD) or binary format. It can
monitor as many as 32 tap positions with one or three
neutral tap positions. Additionally, it monitors the raise
and lower controls to assert alarms for tap position
change failures or unexpected tap positions.
