provide an appropriate protection

curve when non-reclosingoperation is required.

For example:

When Auto Reclose is OFF

When closing onto a fault.

In Single Shot Mode the controllergoes directly to lockout after one

trip and will not Auto-Reclose.

Single Shot - Summary

An ACR will always go directly to

Lockout following a protection trip

if it is in Single Shot mode.

Providing the Work Tag has not

been applied, an ACR will be in

Single Shot mode if:

Auto Reclose is OFF

An operator has closed onto afault. Providing:

-The Single Shot Timer has not

been set to zero.

The timing of a trip that occurswhen the ACR is in Single Shot

mode is determined by dedicated

Single Shot settings for the

particular type of fault.


12/18


Work Tag

Applying the Work Tag ensuresthat closing cannot take place at

all, either by a local operator, aremote operator or automatically.

The switchgear cannot closewhile the Work Tag is applied but

Work Tag can be applied whenthe switchgear is closed providingnothing is inhibiting tripping.

If a protection trip occurs while theWork Tag is applied, theswitchgear will always go tolockout even if Auto Reclose isON.

The protection pickup and time to

trip will be determined by theWork Tag protection settings andWork Tag Trip will be recorded in

the Event Log.

Work Tag and Controller Mode

The controller is always in either

Local or Remote mode.

Only a local operator can

apply/remove the Work Tag when

the controller is in Local Mode.

Only a remote operator can

apply/remove the Work Tag when

the controller is in Remote Mode.

This means that for a local

operator to remove the Work Tag

which was applied by a remote

operator, they must first put the

controller into Local mode. OPERATOR CONTROLSWork Tag AppliedWORK TAG DENIED- CHANGE TO LOCALSELECT to continue

Single Shot and Work Tag Modes

Single Shot and Work Tag modeswill both cause an ACR to go

directly to Lockout if a protectiontrip occurs.

i.e.

-They both prevent automatic

reclosing.

Work Tag mode prevents manualclosing as well.

Single Shot and Work Tag tripsoccur according to their own

respective settings.

i.e.

-In Single Shot mode the ACRwill trip according to the Single

Shot settings.

-In Work Tag mode the ACR willtrip according to the Work Tagsettings.

An ACR will always be in WorkTag mode if the Work Tag isapplied regardless of the SingleShot status.
