7.10. Ground High Current Lockout (50G-2)
The EVRC2A has a ground high current lockout element. The ground high current lockout
element in the EVRC2A, is set based on CT secondary current as connected to the current inputs.
The ground high current lockout element provides a definite time delay versus current.
The operating time of ground high current lockout overcurrent element should be set for equal to
or faster than the ground high current trip element. The ground high current lockout element is
enabled in the Primary, Alternate settings and both [PROTECTION ENABLED] and
[GROUND ENABLED] in user interface panel. The ground high current lockout is not affected
by the cold load pickup scheme.
The ground high current lockout element in the following five settings should be enabled for
ground high current lockout.
PRIMARY SETTING / PROTECTION / H/C LOCKOUT-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 LOCKOUT-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 LOCKOUT-GND / Pickup(A)
Range
10 ~ 20000 A
Default
8000
Step
1A
Set the pickup current of Ground High Current Lockout Element.
This value is the minimum operating current of Ground High Current
Lockout Element.
