Protection Control Settings ON/OFF

The existing ON/OFF controls for the

Protection Control Settings are global.

-Protection

-Auto Reclose

-Negative Phase Sequence Protection

-Earth Fault Protection

-Sensitive Earth Fault Protection

i.e. Once configured they will apply

regardless of which protection group

is active.

Extended Protection functionality

will allow the ON/OFF status for these

settings to be determined by the

active protection group.

When Extended Protection isenabled, each protection group

Maximum Time

The second of the Extended

Protection features changes the

way the Maximum Time settingcan be used.

Normally there is only one Maximum

Time setting for each protection

Group.

Maximum Time is a Global setting

which means that it applies to all trip

settings in that group which use an

inverse curve for timing.

Extended Protection provides a

separate Maximum Time setting for

each inverse curve that has been

applied. (Max 18)

Extended Protection reduces the

minimum value for Maximum Time

settings from 2.0s to 0.2s.

Extended Protection Features - Summary

Each Protection Group has its own

default Protection Control settings

which become active when thatProtection Group becomes active.

An operator can change the active

protection control settings but if the

changed settings are different to the

default setting for the active Protection

Group they will only survive until:

-The active Protection Group is changed.

-Another setting change is made to the

active settings.

A separate Maximum Time setting can

be configured for each trip curve. The minimum Maximum Time setting is

0.2s.

Extended Protection features are

disabled by default.
