SEL-700G Relay
Installation
I/O Configuration
Current/Voltage Card
Option (3 ACI/2 AVI)
MOT…x72x… (1 A phase CTs) or …x76x…(5 A phase CTs).
This card
is only supported in Slot
E
of the SEL-700G1+ model (refer to Table 1.1 and
Figure 2.2). It supports Y-side current inputs for three-phase CTs. It also
supports a synchronism-check voltage input VS and neutral voltage input VN.
Current Card Option
(3 ACIE)
MOT…x73x… (1 A phase CTs) or …x77x…(5 A phase CTs).
This card
is only supported in Slot
E
of the SEL-700G1 base model (refer to Table 1.1
and Figure 2.2). It supports Y-side current inputs for three-phase CTs.

WARNING
Before working on a CT circuit, first
apply a short to the secondary
winding of the CT.
NOTE:
When the
VS-NS
or
VN-NN
voltage inputs are unused in the
SEL-700G1+ model and the setting
DELTAY_X := DELTA, then one of these
voltage inputs could be used to
connect an external zero-sequence
voltage. In such an application, the
setting EXT3V0_X must also be set
accordingly. Refer to
Protection and Logic Functions
for
more details.
