DESCRIPTION
interrupter. This factor is set according to the type of Circuit Breaker used
I^ Maintenance 10 02 Alarm Disabled
Alarm Enabled
Setting which determines if an alarm will be raised or not when the cumulative I^ maintenance counter threshold is exceeded.
I^ Maintenance 10 03 1000
From 1 to 25000 in steps of 1
[Courier Number (current)]
Setting that determines the threshold for the cumulative I^ maintenance counter monitors.
I^ Lockout 10 04 Alarm Disabled
Alarm Enabled
Setting which determines if an alarm will be raised or not when the cumulative I^lockout counter threshold is exceeded.
I^ Lockout 10 05 2000
From 1 to 25000 in steps of 1
[Courier Number (current)]
Setting that determines the threshold for the cumulative I^ lockout counter monitor. Set that should maintenance not be carried out, the
IED can be set to lockout the auto-reclose function on reaching a second operations threshold.
No. CB Ops Maint 10 06 Alarm Disabled
Alarm Enabled
Setting to activate the number of circuit breaker operations maintenance alarm.
No. CB Ops Maint 10 07 10
From 1 to 10000 in steps of 1
[Unsigned Integer (16 bits)]
Sets the threshold for number of circuit breaker operations maintenance alarm, indicating when preventative maintenance is due.
No. CB Ops Lock 10 08 Alarm Disabled
Alarm Enabled
Setting to activate the number of circuit breaker operations lockout alarm.
No. CB Ops Lock 10 09 20
From 1 to 10000 in steps of 1
[Unsigned Integer (16 bits)]
Sets the threshold for number of circuit breaker operations lockout. The IED can be set to lockout the auto-reclose function on reaching a
second operations threshold.
CB Time Maint 10 0A Alarm Disabled
Alarm Enabled
Setting to activate the circuit breaker operating time maintenance alarm.
CB Time Maint 10 0B 0.1
From 0.005 to 0.5 in steps of 0.001
[Courier Number (time-seconds)]
Setting for the circuit operating time threshold which is set in relation to the specified interrupting time of the circuit breaker.
CB Time Lockout 10 0C Alarm Disabled
Alarm Enabled
Setting to activate the circuit breaker operating time lockout alarm.
CB Time Lockout 10 0D 0.2
From 0.005 to 0.5 in steps of 0.001
[Courier Number (time-seconds)]
Setting for the circuit breaker operating time threshold which is set in relation to the specified interrupting time of the circuit breaker. The
IED can be set to lockout the auto-reclose function on reaching a second operations threshold.
Fault Freq Lock 10 0E Alarm Disabled
Alarm Enabled
Enables the excessive fault frequency alarm.
Fault Freq Count 10 0F 10
From 1 to 9999 in steps of 1
[Unsigned Integer (16 bits)]
Sets a circuit breaker frequent operations counter that monitors the number of operations over a set time period
Fault Freq Time 10 10 3600
From 0 to 9999 in steps of 1
[Courier Number (time-seconds)]
Sets the time period over which the circuit breaker operations are to be monitored. Should the set number of trip operations be
accumulated within this time period, an alarm can be raised. Excessive fault frequency/trips can be used to indicate that the circuit may
need maintenance attention (e.g. Tree-felling or insulator cleaning).
