Processing a PQ Event Record
The worst excursion RMS values are specified as ADC values, and to convert them to
primary, you use the same primary value formula provided under Processing a Wave-
form Capture on page B-47.
PQ events come with numerous PQ records. From this numerous set, normally there
exists a specific pair of PQ records (special cases will be discussed later), one that is
created at the beginning of the PQ event and one created at the end of the PQ event -
- an Out and Return PQ record. Using these two records along with all the other PQ
records in between them, you will be able to calculate the duration of the PQ event.
To further elaborate, whenever an "out" event happens (i.e., when a voltage surge or
sag occurs), the "Out" PQ Record for that PQ event is created. Likewise, when this
said "out" event returns (i.e., the voltage surge or sag returns to normal levels), the
"Return" PQ Record for that PQ event is created. From these two particular PQ
