Fig. 3-2-36 Zero current alarm parameters
Fig. 3-2-37 Over ground current alarm
parameters.
'1.000A' indicates the primary side limit value
of the zero-current alarm.
The '1.100A' represents the primary side return
value of the zero-current alarm.
The '600' indicates that the delay time of
zero-current is 600ms.
Note: the default value of zero
-current
alarm
allows to be not allowed; The default value of the correlation relay is not associated; The
default value is 0A; The default value of the return value is 200A; The default value of
the delay time is 60000ms.

Over ground current alarm
parameters.
The word "w-et" is displayed on the top of the screen to
indicate the alarm parameters of over ground current.
When the over ground current alarm is not allowed, the
screen is shown in fig. 3-2-37: 'OFF' indicates that the over
ground current alarm is not allowed.
When the over ground current alarm is allowed,
the screen is shown as shown in fig. 3-2-37: '1'
indicates that the over ground current alarm relays 1.
'6.000A' represents the primary side limit value
of the over ground current alarm.
The '5.400A' indicates primary side return
value of the alarm.
The '600' indicates that the delay time of over
ground current is 600ms.
Note: the
over ground current
alarm allows the default value to be not allowed;
The default value of the correlation relay is not associated; The default value is 6000A;
The default value of the return value is 5000A; The default value of the delay time is
60000ms.
