Metering and Monitoring
Metering
Table 5.3 shows the thermal meter values. To use external SEL-2600 RTDs
configure the port protocol (PROTO := RTD) and metal type (RTDxT := PT100,
NI100, NI120, or CU10, where x is 1 to 12) settings.
The thermal meter function also reports the state of connected RTDs or TCs if
any have failed. Table 5.4 shows failure messages and their meanings.
RTD/TC Metering
The thermal metering function reports the present values of the RTD and/or ther-
mocouple input temperatures when using the internal general purpose RTD/TC
card. Figure 5.2 shows the device response to the MET TEMP command.
The thermal meter function also reports the state of connected RTDs/TCs if any
have failed. Table 5.5 shows failure messages and their meanings.
Fundamental
Metering
Table 5.6 details each of the eight cycle-averaged meter data types in the
SEL-2414. These values are listed if the appropriate cards are installed and if
they are not inhibited by the type of transformer connection (see Transformer
Nameplate Application Description on page 5.11 for more information).
