Extended Standard Detection

This feature is used when it is required to have different Detection Control settings associated with each configured detection group.

Detection Control settings include:

• Detection On/Off

• Sectionaliser On/Off

• NPS Detection Sectionalise/Alarm/Off

• EF Detection On/Off

• SEF Detection On/Off

• SEF Alarm On/Off

• Single Shot Mode On/Off

In normal operation that is with Extended Standard Detection Off, these settings are global. That means that once they have been configured on the WSOS Control page they become operational regardless of which detection group is active.

Extended Standard Detection functionality allows the On/Off status for these settings to be determined by the active detection group.

Selecting Extended Standard Detection On, immediately adds Detection Control settings to each configured detection group.

The Control page always displays the operational Detection Control settings that is the settings that are in service at the time.

Another set of Detection Control settings now appears on the Global Settings page for each configured detection group. See figure below.

The settings in the figure above labelled Extended Detection Settings are the DEFAULT detection Control settings for that group. These default settings can be configured differently for each detection group.

When the active detection group is changed, the default Detection Control settings for the group that becomes active become the operational Detection Control settings and appear on the Control page.

So if Group A is active and the operational Detection Control settings are:

• Detection On

• Sectionalise Off

• NPS Detection Off

• EF Detection Off

• SEF Detection Off

• SEF Alarm Off

• Single Shot Mode Off

Then Group B is made active and the Group B Default Detection Control settings are:

• Detection On

• Auto Reclose On

• NPS Detection Trip

• EF Detection On

• SEF Detection On

• SEF Alarm On

• Single Shot Mode On

The appearance of the Control page will change as shown in the figure below:

It can be seen from the above figure that when the active detection group was changed from A to B, the Group B default Detection Control settings became the operational settings shown on the Control page.

These default settings are referred to as non-volatile as they will be retained in the detection group settings despite changes to the operational settings when their group is active.

QAK/Quick Keys

If changes are made to any of the operational Detection Control settings using the QAK/Quick Keys, the changed setting will stay in force until either:

• The detection group is changed, or

• It is changed by the operator again.
