Events Related to Tank Leakage Protection (64T)
Time Delay Before Trip
If a pickup occurs, the time delay (set in Address 2725) starts. If
this setting is zero, this event never occurs. Any outputs
marshalled to this event will remain energized until the time delay
expires.
Tank T start 5916 C S T
Trip
If the element is still in pickup when the trip time delay (if any)
ends, the element will trip. With the default marshalling, LED 1 and
LED 8 will light and latch. Any outputs marshalled to this event will
remain energized until the element resets (event 5917:G). If the
operational status is “Block Tripping,” the trip event will occur, be
logged, and affect any LEDs it is marshalled to, but it will not
energize any output signal or trip (command) contacts.
Tank Gen.Trip 5921 C S T
If a 64T trip occurs, the value of the tank leakage current
(fundamental component) at the time of the trip is recorded in the
open fault log.

Configuration Errors
This event occurs if an attempt is made to save the settings with
the tank leakage protection set to exist (Address 7827), but other
settings make tank leakage protection unavailable (for example,
the protected object has three windings or sides). Lights LED 14 on
a 7UT513 with default marshalling.
