SECTION 12
Analog Quantities
This section contains tables of the analog quantities available within the SEL-421
Relay.
Use Table 12.1 and Table 12.2 as a reference for labels in this manual and as a
resource for quantities you use in SEL
OGIC control equation relay settings.
Table 12.1 lists the analog quantities alphabetically, and Tab le 12.2 groups the
analog quantities by function.
