Major Address Block Operation Steps
(Contirued)
3.7.1
Device Configuration (Address 1000)
Use this address block to configure the ISGS relay to match
the line frequency, phase
sequence, and
breaker connection
settings fcr your system. The
ava~able
relay subaddresses
are listed in Table 3.6. To make parameter changes, yoo
rTILSt trst enter the passwcrd. If you orty want to review the
present settings, the password steps 4 and 5 are not neces-
sary.
Perform parameter changes using steps 1-9 of the
standard operation sequence, Toole 3.4.
Note:
Do not change device configuration (Table 3.6)
wh~e
the relay is in service, as the relay can require up to 30 sec-
onds to reinitialize for this change. Durng reinitialization, the
relay does not provide protection.

The breaker connection parameter
(1
004) defines which
ootput contact (Trip
1
or Trip 2) is connected to open the cir-
cuit breaker. This information is used by the breaker failre
ft.nction,
if
that ft.nction is enabled (see section 3. 7 .14).
Also, refer to the discussion on matrixing in section 3.

Use this address block to configure the ISGS relay to match
the Phase
CT
Primary Rating and Neutral or Grot.nd
CT
Pri-
mary Rating settings, and the
CT
input's Norm Power Row
settings to match your system. The available relay subad-
dresses are listed in Table 3.7.

To make parameter changes, you must first enter the
pass-
word.
If
you only want to review present settings, the pass-
word steps 4 and 5 are not
necessary
Perform parameter
changes using steps 1-9
of
the standard operation
sequence, Toole 3.4.
Note:
Do not change
CT
configuration (Table 3.7)
wh~e
the
relay is in service, as the relay can require up to 30 seconds
to reinitialize for this change. During reinitialization, the relay
does not provide protection.

The phase

CT
primary rat-
ings are independently configurable. However, when a resid-
ual sensing method is used for ground taut protection, the
primary current ratings for the neutral
CT
and the phase
CT
must be equal.
Power flow conventions (1104) are defned such that "Nor-
mal" power low is into the phase
CT
polarity mark, and
"Reverse" power ftow is out
of
the phase
CT
polarity mark.
Figure 3.2 illustrates exafll)les
of
