SELCO G-Line for
Land-based Applications
SELCO’s new G-Line Generator Protection Relays are mainly intended for use in
land-based applications. The G-Line range of relays provides an efficient solution in
applications where cost of materials is the main issue.
Despite a low cost, the G-Line relays still provide a number of ground-breaking
features not presently offered by the competing relays.
Installation
The SELCO G-Line Generator Protection
Relays are easy to install. The relays are
housed in a compact enclosure for DIN
rail mounting or fixation by two ordi-
nary screws. The design matches that of
the well proven SELCO T-Line product
range.
Configuration
Configuration and setup is easier than
ever. Despite the use of modern micro-
processor technology, adjustment dials
are maintained in order to make confi-
guration and test as easy as possible.
The reference current, voltage or frequen-
cy is easily set by briefly activating a
small push button (PRESET).
Indications and Relays
The state of the contact sets inside the re-
lay is clearly indicated by LEDs located
on the front plate. There is one LED for
power, one LED for pick-up (activates
when the set-point is exceeded) and one
LED to indicate the state of the trip relay.
The pick-up relay has one contact set
and the trip relay has two contact sets.
One relay covers all voltages
One variant covers all voltages (nominal
63 to 690V AC). An external supply of
+24V DC is required.
Advanced Configuration
The SELCO G-Line Generator Protection
Relays provide the optional feature of
advanced PC based configuration (using
a standard ANSI terminal). An optional
programming kit (G0100) will allow the
user to reconfigure the function of the
relay, as well as the minimum/maxi-
mum scales of the dials.
This makes the G-Line relays even
more flexible and versatile to customers
requirering adapted functionality. The
front plate of the relay can be custom-
ized as well.
Design
G-Line relays are single function units.
The single variant principle is an advan-
tage, as one version covers all voltages.

However, it is possible to choose (using
the optional programming kit G0100)
whether the relay is for e.g. under-
current or overcurrent.
Features include a level preset function
(for reference definition), all optional
functions onboard (e.g. latching), PC
based configuration of scales, set points
etc.
