Real-Time and Min./Max. Measurements
The P_SE OCR records historical maximum and minimum measurement values alongside real-time measurements.
Some historical values may be manually reset, include User and OCR timestamps, and/or are unique to MCCB
’s
with Neutral reference (3Ph+N) or without
(3Ph) depending on system topology. The properties of each type of available historic values are indicated in the following table.
For example, the “Max
imum since reset of minimum of I
1
, I
2
, I
3
” describes the highest I
min
value calculated/measured since the last manual reset of historical
values. If reset, the existing instantaneous I
min
value will become the new maximum of I
min
since reset and will be updated accordingly.
