The SEL-2414 monitor data fall into the following categories:
Thermal Element
Application Description
The SEL-2414 provides a thermal element based on IEEE Standard
C57.91-1995, IEEE Guide for Loading Mineral-Oil-Immersed Power Transform-
ers. Use this element to activate a control action or issue a warning or alarm when
your transformer overheats or is in danger of excessive insulation aging or loss of
life. Capture current hourly or daily data about your transformer using the ther-
mal event report. The data acquisition interval is one minute. This very short time
interval makes the element suitable for both thermal protection and control func-
tions.
