Overview
IMPORTANT: Upon relay initial
power up or Port 1 setting changes or
Logic setting changes, the user may
have to wait up to two minutes before
an additional setting change can
occur. Note that the relay is functional
with protection enabled, as soon as
the ENABLED LED comes ON (about 5–10
seconds from power up).
The SEL-787 Transformer Protection Relay stores the settings you enter in
nonvolatile memory. Settings are divided into the following eight setting
classes:
1. Group
2. Logic
3. Global
4. Port p (where p = F, 1 [Ethernet], 2, 3, or 4)
5. Front Panel
6. Report
7. Modbus
®
8. DNP3
Some setting classes have multiple instances. In the above list, there are five
port setting instances, one for each port. Settings may be viewed or set in
several ways, as shown in Table 6.1.
Setting entry error messages, together with corrective actions, are also
discussed in this section to assist in correct settings entry.
The SEL-787 Settings Sheets at the end of this section list all SEL-787
settings, the setting definitions, and input ranges. Refer to Section 4:
Protection and Logic Functions for detailed information on individual
elements and settings.
