7.7. Ground High Current Trip (50G-1)
The EVRC2A has a ground high current trip element. The ground high current trip element in the
EVRC2A is set based on CT secondary current as connected to the current inputs. The ground
high current trip element provides a definite time delay versus current.
The operating time of ground high current trip overcurrent element should be set for equal to or
faster than the ground time overcurrent elements. The ground high current trip element is enabled
in the Primary, Alternate settings both
[PROTECTION ENABLED]
and
[GROUND
ENABLED]
in user interface panel. Ground high current trip is not affected by the cold load
pickup scheme.
The ground high current trip element in the following five settings should be enabled for ground
high current trip.
PRIMARY SETTING / PROTECTION / H/C TRIP-GND / Function
Range
OFF, TRIP, TR&AR
Default
OFF
Step
~
If function = OFF,
the feature is not operational.
If function = Trip,
the feature is operational. When the feature asserts
a TRIP condition, Trip operates.
If function = Trip & AR,
the feature is operational. When the feature
asserts a TRIP & AR condition, it trips and alarms.
PRIMARY SETTING / PROTECTION / H/C TRIP-GND / Relays(0-8)
Range
OFF, 0 ~ 8
Default
OFF
Step
1
Selects the required relays to operate when the feature generates a Trip.
PRIMARY SETTING / PROTECTION / H/C TRIP-GND / Pickup(A)
Range
10 ~ 20000 A
Default
4000
Step
1A
Set the pickup current of Ground High Current Trip Element.
This value is the minimum operating current of Ground High Current
Trip Element.
