RTD-Based Protection
When you connect an SEL-2600 RTD Module (set E49RTD := EXT) or order
the internal RTD card (set E49RTD := INT) option, the SEL-700G offers
several protection and monitoring functions, the settings for which are
described in Table 4.45. See Figure 2.11 for the RTD module fiber-optic cable
connections. If the relay has no internal or external RTD inputs, set
E49RTD := NONE.

NOTE:
The SEL-700G can monitor as
many as 10 RTDs connected to an
internal RTD card or as many as
12 RTDs connected to an external
SEL-2600 RTD Module. Table 4.45
shows the location, type, and trip/
warn level settings for RTD1; settings
for RTD2–RTD12 are similar.
NOTE:
RTD curves in SEL products
are based on the DIN/IEC 60751
standard.
