Low-Level Test
Interface
The SEL-700G has a low-level test interface on the 4 ACI/3 AVI current/
voltage card, 1 ACI neutral current card, or 3 ACI current card (Slot
Z
) and
3 ACI/4 AVI current/voltage card, 2 AVI voltage card, 3 ACI current card, or
3 ACI/2 AVI current/voltage card (Slot
E
). You can test the relay in either of
two ways: conventionally by applying ac signals to the relay inputs or by
applying low magnitude ac voltage signals to the test interface on the printed
circuit boards.
You can use the SEL-RTS Low-Level Relay Test System to provide signals to
test the relay. Figure 10.1 shows the Test Interface connectors. Figure 10.2
shows the Cable C700G connection between an SEL- RTS test system and the
SEL-700G.

The SEL-RTS Relay Test
System consists of the SEL-AMS
Adaptive Multichannel Source and
SEL-5401 Test System Software.

NOTE:
The SEL-700G Relay can
have as many as 14 analog input
channels. The SEL-AMS has only as
many as 12 analog input channels.
This is the reason for C700G cable
complexity.
