Fault Recording
Logic expressions define the three conditions that determine when a fault has occurred. See Figure
14-30. When a fault is detected by the relay, the relay records (stores in memory) data about the fault.
The three conditions that determine a fault are Trip, Pickup, and Logic Trigger. To define these
conditions, click on Fault Recording, Logic box. Then click on Tripped, Picked Up, and Logic, in turn, and
program the inputs that define each condition. You may clear existing programming by clicking on the
Clear button or clicking on each individual variable.
The fault recording function can record up to 16 oscillographic records in volatile memory. Because there
is only a specific amount of memory available, as additional faults are recorded, the oldest records are
overwritten. Each record can record only a limited number of data cycles. If you have less than 16
records, you can have more than 15 cycles of data per record. To select the number of cycles of data and
number of records, click on the Oscillographic Records, Select button and click on the number of records
that you want to record.
Logic settings for the Target Reset Logic can be made by clicking on the Target Reset - Logic button and
then clicking on the Reset input. Other logic blocks shown under BESTlogic on the Alarms tab are shown
for reference only. There is no interaction available.
Any protective function, except 62, 162, and 60FL that has a trip will set a target because these functions
have the targets enabled on the Fault Recording tab. If you are using a protective function in a
supervisory capacity and do not want to set a target when the protective function trips, disable that target
by clicking on the specific target. If you want to disable all of the targets for a function such as the inverse
time overcurrent functions, click on the No 51's button on the left side of the Enabled Targets pane.
