APPENDIX 2. INTEGRATOR (IT) BLOCK
A2.5 Output Process
There are the following three output parameters:
1. OUT
2. OUT_TRIP
3. OUT_PTRIP
Parameters OUT_TRIP and OUT_PTRIP are used only
when INTEG_TYPE is a value from 1 to 4.
In case of Integrator block related memory failed, the
status of OUT, OUT_TRIP, OUT_PTRIP becomes
“Bad-Device Failure”.
OUT.Value, OUT_TRIP.Status, and
OUT_PTRIP.Status are determined by the ratio of the
"Good" integrated values to all integrated values,
which is stored in PCT_INCL (0% to 100%). The user
must set the threshold value of each status to
UNCERT_LIM and GOOD_LIM.
The Integrator block determines the status of the output
using the three parameters: PCT_INCL,
UNCERT_LIM, and GOOD_LIM.
䊉 PCT_INCLGOOD_LIM
⇒Good
䊉 UNCERT_LIMPCT_INCLGOOD_LIM
⇒Uncertain
䊉 PCT_INCLUNCERT_LIM
⇒Bad
If INTEG_TYPE is 5, 6, or 7, the status of the trip
output becomes "Good-NS-Constant."
0% UNCERT_LIM GOOD_LIM 100%
PCT_INCL
GOOD
Uncertain
Bad
PCT_INCL=100(1 - (msp of RTotal)/(msp of ATotal))
msp of RTotal: RTotal value that is converted into a short floating-point number
msp of ATotal: ATotal value that is converted into a short floating-point number
RTotal: Integrated value of the absolute values of the increments whose status is bad
ATotal: Integrated value of the absolute values of the increments regardless of the output status

The same criteria for determining the status of the
output of the Integrator block are used in common for
the above three parameters.
